2.10.2.2 Receiver Section

The Receiver is a fully coherent triple conversion super heterodyne Receiver with RF gain. Two Receiver paths are provided, one for Target processing and the second for Weather processing. These two paths have identical RF, IF, and Video components.

The Receiver consists of RF Assembly, Target Downconverter Module and Weather Downconverter Module.

The RF Assembly consists of the RF Front End and the Interface/Regulator Card. The RF Assembly accepts three S-band receive signals (2700 to 2900 MHz) from the Microwave Assembly consisting of a Target High Beam, Target Low Beam and Weather High/Low Beam. The Target processing path provides for high or low beam selection after RF amplification. The RF Assembly also accepts S-band test signals from the Stability Monitor for Online Receiver performance monitoring. The target, weather and test signals are sent through STC and low noise amplifier circuits before being downconverted to IF frequencies in the DCONs.

The STC/Gain control in the RF assembly section uses digitally controlled Attenuators to maintain Receiver linearity and prevent saturation due to strong clutter returns. These Attenuators are controlled by the ASDP through the Interface/Regulator card. The Interface/ Regulator card receives the Beam STC control signals from the ASDP, reclocks and delays these signals and applies them to various components in the RF Assembly, except for the Weather Beam control which is sent to the Antenna Group.

The IF signals are then fed to ADCs, the digital outputs of which are further processed to remove the dc level and generate 14-Bit I and Q signals. These I and Q signals are sent out sequentially to both ASDPs, as 15 Bit words after being twos complemented in the I/Q Splitter (Processor).

2.10.2.3 BITE Section The REX supports fault monitoring and isolation test routines that are executed in the ASDP. Online fault monitoring routines are used to detect Receiver faults and Offline fault isolation diagnostics and specific test routines are run sequentially to locate functional faults. The REX is functionally partitioned to allow the diagnostic routines to locate faults to a LRU.

2.10.2.3.1 REX Fault Monitoring The BITE section includes the Stability Monitor, see Figure 2-39. The Stability Monitor is used to select one sample from the UCON, Transmitter Driver or Transmitter output. The selected signal is delayed by 5 μs, then amplified and fed to the Receivers or to the DCON through an ASDP controlled switch.

Online Receiver fault monitoring and detection uses one of the three RF diagnostics S-band test signals. This test signal is injected, before the digitally controlled Attenuators, into each Receiver path through a power divider and 30 dB Directional Couplers. The test signals are used to verify Receiver high target, low target and weather channel continuity, gain, and A/ D noise level.

Online stability fault monitoring and detection also uses the three RF diagnostic S-band test signals. The signals are injected at an effective front end signal-to-noise level of 56 dB, through a switch into the DCON of each Receiver path. These RF test signals are used to verify the combined REX and Transmitter output phase stability.

The SCDI provide a “numerical test values” screen as a submenu for each REX/ASDP. This screen permits the operator to check the calculated system stability and end-to-end test values,

In each RF Module, the bandwidth of the Receiver is reduced by Bandpass Filter FLI, which follows the Coupler/Attenuator. The Filter has minimum insertion loss of 0.2 dB in the frequency range 2.7 to 2.9 GHz. This Filter prevents strong out-of-band signals from saturating the Receiver, and from producing unwanted signals in the passband. This Filter also attenuates the image frequency (minimum attenuation of 65 dB) and the first IF frequency (minimum attenuation of 75 dB). The Filter out-of-band specifications are limited by the desire to maintain the lowest possible insertion loss in the passband, in order to minimize the noise figure.

In-band signals are amplified and limited by the low noise Amplifier/Limiter AR1, which follows the Bandpass Filter. The Low Noise Amplifier (LNA) amplifies the RF signal while degrading the Signal-to-Noise Ratio (SNR) by the amount of the noise figure. In order to minimize noise contribution, an LNA with the lowest possible noise figure was selected.

To further reduce the noise figure of the following stages, the gain of the LNA is as high as possible. (Although higher gain reduces the noise contribution, it adversely affects the dynamic range of the following stages.) The gain selected for the LNA provides maximum dynamic range with minimum noise figure. An LNA with a gain of 27 to 30 dB and a noise figure of 0.7 dB provides the optimum performance.

The limiting portion of AR1 allows the noise floor of each of the Receiver paths to be matched within +/- 0.5 dB.

The outputs from the RF Assembly are sent to the DCONs. The weather channel output is sent directly to the Weather DCON. The Target High and Low channel outputs are first multiplexed into one output before being sent to the Target DCON. The multiplexing operation is performed at S2, a SPDT switch. The Beam/STC/Azimuth function in the ASDP, controls switch S2. Control signals to S2 are in TTL format.

Fault isolation for the RF Assembly is directed by the SPTT RF Switch S1, Power Dividers PD1 and PD2, and the Directional Couplers built into Z1 of each beam channel. Switch S1, in conjunction with PD1, provides selection of injection into either the front end of the Receiver, or in conjunction with PD2, injection into the Target and Weather DCONs. Control signals to S1 are in TTL format.

2.10.3.1 Interface/Regulator CCA See Figure 2-43 and refer to schematic diagram in section 7. The RF Assembly includes Interface/Regulator CCA A4 which provides voltage regulation (for RF Assembly and the Stability Monitor), reclocking of control signals, manual adjustment of control line delay, and cable interfacing. These functions are provided primarily for the devices on the RF Assembly, but also provide control to the Weather High/Low Beam switch located at the Antenna.

The 5.18 MHz clock received from the Local Oscillator is divided by four in a synchronous counter to obtain a 1.29 MHz range clock. The counter operation is aligned in time by the A/D Sync Strobe from the Waveform Generator.

The control signals from the ASDP are received as RS-422 through line Receivers. RF ATTEN (weather), RF ATTN (target), Target Beam Control, and WX Beam Control are reclocked in two stages. The first stage of reclocking uses the range clock (1.29 MHz). The second stage uses the range clock delayed by a time range from 0 to 700 ns, which can be selected in 100 ns increments. Each control signal referenced above has a separate delay selection circuit.

The input data is converted to floating point. The number of Finite Impulse Response (FIR) filters equals the number of Radar pulses in the CPI. The center frequencies of the filters are provided in Table 2-12. Each filter has eight sets of coefficients available. Each FIR filter output is a complex vector of length equal to the maximum range of the Radar, where the vector will contain a value for each 1/16th of a nmi.

For each FIR (Doppler filter), the five complex input samples for each CPI are applied to the complex filter coefficients. The output magnitude of each filter will be weighted by the match of the input signal to the Doppler center of each filter. The magnitude will be greatest from the filter whose Doppler center is closest to the Doppler velocity of the target.

In the five pulse system, there are four filters that are centered on non-zero Doppler values. These filters have two possible curves based upon the clutter environment. This function is the range adaptivity function, and it allows the Doppler filters to adaptively change their low Doppler sensitivity on an Azimuth segment basis. For each 1.4° Azimuth segment, the range adaptivity algorithm scans the corresponding clutter map segment from maximum range to minimum range to identify the range at which the clutter map cell amplitude exceeds a predetermined clutter value.

For ranges beyond this range cell value the Doppler filters will allow slightly more gain for targets with Doppler, but will have a sharp filter cutoff at zero Doppler. Within this range, the filters are switched to allow increased low Doppler rejection when clutter is present.

The Doppler filter coefficients also operate in Azimuth adaptivity mode which is used for AP (anomalous propagation) filtering. There are four Azimuth adaptive sets of filter coefficients that are available. For each 1.4° azimuth segment (256 per scan), one of the four sets of filters can be applied to each CPI. When the function is applied filter selection is based upon the contents of a site pre-programmed map generated by an Offline tool. The MAP function supplies the value to the DSP, allowing AP filtering to be applied only in affected areas as required.

DSP, Log-Mag. The log-mag processing takes the magnitude (or magnitude squared) of each range gate and calculates its logarithm. To save processing time, this process uses an approximation.

The log-magnitude outputs of non-zero filters are then fed into a CFAR process to minimize the number of false alarms. The zero Doppler filter outputs are fed to a clutter map generation process, which generates a range-azimuth map of the clutter.

5.3.7.9 Weather Beam Switch Test

The purpose of this test procedure is to verify the operation of the weather beam switch. The beam switch will be tested by manipulating the weather beam switch selection utilizing the REX/SDP Equipment Control Screen. By changing from Weather Hi Beam and monitoring clutter return with the Radar Data Display (RDD), then changing to Weather Lo Beam while monitoring the RDD. A functional Weather Beam switch will display increase clutter amplitude at a known point when changing from Weather Hi beam to Lo Beam. This procedure is required because there is no signal available from the weather beam switch to indicate that the switch has operated as commanded. This procedure is typically run at the same time as Wx Optimization or can be performed when Weather Beam Switch operation is suspected as a fault.

NOTE: This procedure should be performed on a clear day with no weather out to twice the range of the PSR.

Performance of this procedure will require both PSR REX/SDPs to be in Maintenance causing loss of primary radar data. Coordination with Air Traffic is required.

Figure 6B-7 Interface Regulator Card component locations.

a. Clocks:

1. 518 MHz clocks arrive at J10.

2. R9 provides Z matching.

3. U12A and U12B are Schmidt triggers to shape the pulses.

4. 5.18 MHz pulses go to U5 and U19 and CLK MON output J17(front of card).

5. U5 is a divide by 4 binary counter.

6. U5 pin 13 outputs are Range Clocks at 1.29 MHz.

7. SYNC STROBE pulses arrive at J9.

8. R10 provides Z matching.

9. U12C and U12D are Schmidt triggers to shape the pulses.

10. The SYNC STROBE pulses occur at 1.295 MHz and are applied to the Clear Not input of U5 to time-align the 1.29 MHz range clocks.

11. The 1.29 MHz clocks are applied to U1, U3A, U4A, U6, U19, and to delay line U10.


G584380 Rev. F3, April 2011

b. Thermal Switch:

1. There is a temperature sensitive switch, S1, located on the Interface / Regulator CCA, It is set to open at 150° F. (65.5° C) and close at 140° F (60° C).

c. Target Beam Switch Control:

1. Target Beam Switch settings come from the ASDP, These settings arrive as RS-422 signals to U20 and are converted to TTL levels.

2. From U25 they go to the J2 pad for pin 10 then by U13 and U14 to D Flop U3A.

3. U3A clocks the signal at a 1.29 MHz rate corresponding to a “Range Gate”.

4. The clock to U3B is also at 1.29 MHz but it is delayed by 500 ns. Thus U3B holds the clock pulses for an additional 300 ns to compensate for the switching time for the S2.

5. Note that output from U3A-Q(NOT) is used to control U8 and U9, as well as for controlling S2.

d. Weather Beam Switch Control:

1. Weather Beam Switch Control is cobtrolled using U4A and U4B . The output from U4B is the Q. It is changed from TTL levels to RS-422 by U11 and sent to the Weather Beam Switch in the Antenna. (U11 is subject to issues with surge currents for this reason).

e. Target STC Control:

1. Target STC settings arrive as RS-422 signals to U25 and are converted to TTL levels.

2. From U25 they go to J2 pads for pins 2, 3, 4, & 5 then by U13 and U14 to Quad D Flops U1.

3. U13 contains pull up resistors for each line, U14 provides line termination.

4. U1 clocks the signals at a 1.29 MHz rate corresponding to a “Range Gate”.

5. The clock to U7 is also at 1.29 MHz but it is delayed by 500 ns. Thus U7 holds the clock pulses for an additional 500 ns to compensate for the change time for the STC Attenuator.

6. Low on U8 pin 1 causes it to pass the STC attenuation settings to Target High Beam Z1.

7. Low on U9 pin 1 sets all outputs high putting maximum STC on Target Low Beam Z1.

8. High on U8 pin 1 sets all outputs high putting maximum STC on Target High Beam Z1.

9. High on U9 pin 1 causes it to pass the STC attenuation settings to Target Low Beam Z1.

Additional documentation references: Paragraph 2.10.3 contains a functional description of the RF assembly.

6B.2.6 T-2000 Advanced Lights Out Management (ALOM) troubleshooting
