Receiver Signal Processing
• Acquisition function– Threat acquisition and priority per UDF program– Lookthrough when jamming
• Signal screening– Time of arrival– Pulse width– CW amplitude– Pulse amplitude
• Threat monitor– PRI tracking/prediction– Frame tracking of burst signals– Threat mode changes
4133/020716
Threat Identification
• Threat processing performed per programmable UDF– Parameters are RF, amplitude, signal type, PW and PRI– Directed search via radar warning receiver is an available
feature and programmable in the UDF
• Receiver collects data in designated RF bands– Amplitude settings correlate to threat lethality/range– Analyze signal characteristics to identify threat type
• Lookthrough process enables new acquisitions during jamming– Lookthroughs performed according to threat priority– Parameters are UDF programmable
4133/020716
Single Port Repeater Operation
• Chopped repeater timeshares the same antenna– No isolation / gain reduction requirements needed to
eliminate ring around-oscillation effects– Spectral purity is preserved– Simplifies aircraft installation
• CW transmission uses delay line for velocity only techniques
• PD transmission uses digital RF memory for range techniques
• Simultaneous CW and PD Jamming Capability
