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