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
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
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
