Abstract:

CURRENT, UBIQUITOUS TIME-OF-ARRIVAL (TOA) BASED INTERCEPT RECEIVER PROCESSING CAN BE EASILY DEFEATED BY RANDOMIZING THE RADAR PRI. CURRENTLY DEPLOYED SYSTEMS ALL EMPLOY SOME FORM OF (RELATIVELY) NARROW BANDWIDTH SUPERHETERODYNE-BASED INTERFEROMETER AS THE BASIC INTERCEPT RECEIVER ARCHIETECTURE; ADDITION OF PULSE-TO-PULSE RANDOM FREQUENCY AGILITY WILL FURTHER DEGRADE THE INTERCEPT CAPABILITY. USE OF A RADAR WAVEFORM WITH PSEUDORANDOM TIME AND (PULSE-TO-PULSE) FREQUENCY AGILITIES WILL EFFECTIVELY DENSY INTERCEPT TO THE NARROW BANDWIDTH SUPERHETERODYNE CLASS OF RECEIVER; THERE WOULD BE A LARGE SCAN-ON-SCAN REDUCTION IN PROBABILITY OF INTERCEPT (POI) IN BOTH THE FREQUENCY AND TEMPORAL DIMENSIONS. NEW INITIATIVES IN INTERCEPT RECEIVER DEVELOPMENT INCLUDE WIDE BANDWIDTH (2,000 MHZ) PARALLEL PROCESSING CHANNELIZERS WITH OPTIONAL COLLECTION MODES WHICH CAN PRODUCE UP TO 50 DB OF PROCESSING GAIN. THE DESIGN OF A RADAR WAVEFORM (MODEL) WHICH CAN DEFEAT A TRULY MODERN INTERCEPT RECEIVER WHILE MAINTAINING TARGET ACQUISITION/TRACKING PERFORMANCE REQUIRES INDEPTH UNDERSTANDIG OF RADAR SYSTEMS AND CURRENT INTERCEPT SYSTEMS; PRI HAS THIS EXPERIENCE AND CAPABILITY.
