What is HIRF?

High Intensity Radiated Fields (HIRF)

Generally RF field Strengths 200V/m and above

Source Radar

Radio & Broadcast Transmitters

Communication Transmitters

Commercial & Military Sources

Airborne, Land-Based, Off-Shore Platforms, & Ship based.

Why Test HIRF?

Greater dependence on electronics for safe

flight

Reduced EM shielding of composite materials

Increase in susceptibility of electronics

increased operating speed

higher density

greater sensitivity of electronic devices

Expanded spectrum use above 1GHz.

HIRF environments more severe due to an

increase in the number and power of RF

transmitter
