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
