FUNCTIONAL RECOGNITION OF RADAR SIGNALS

ALGORITHMS WILL BE DEVELOPED THAT PERMIT AUTOMATIC IDENTIFICATION OF NAVY ESM CONTACTS BY FUNCTION. THE ALGORITHMS WILL PROVIDE A COMPUTER-BASED IMPLEMENTATION AND IMPROVEMENT IN TERMS OF RELIABLE IDENTIFICATION AND TIMELINESS, ANALOGOUS TO "THUMB RULES" USED BY OPERATORS TO REPORT EMITTER FUNCTIONS. THE APPROACH WILL IDENTIFY FUNCTIONAL RECOGNITION CATEGORIES IN THE CURRENT AND PROJECTED THREAT SIGNAL ENVIRONMENT AND DETERMINE THE PARAMETER RANGES IN EACH CATEGORY. THE THREAT WILL BE DEFINED IN TERMS OF RADAR FUNCTION AND DECISION ALGORITHMS DEVELOPED FOR USE IN IDENTIFYING THE RADAR FUNCTION FOR CONTACT REPORTING. THE IMPACTS OF PARAMETERS NOT MEASURED BY THE ESM SYSTEM ON FUNCTIONAL RECOGNITION ARE ASSESSED AND POSSIBLE SOLUTIONS IDENTIFIED.
