JAMMING TECHNIQUES AGAINST FREQUENCY HOPPING SIGNALS

THE TECHNICAL OBJECTIVE OF THIS RESEARCH IS TO IDENTIFY AND ANALYZE INNOVATIVE APPROACHES TO JAMMING FREQUENCY HOPPING SIGNALS. JAMMING SCHEMES AND WAVEFORMS WHICH DO NOT REQUIRE PRECISE KNOWLEDGE OF THE VICTIM SIGNAL AND WHICH MINIMIZE THE JAMMER POWER REQUIRED, SUCH AS IMPRECISE FOLLOWER JAMMING, PARTIAL-BAND BARRAGE JAMMING, AND EFFECTIVE SWEEPER JAMMING, ARE OF PARTICULAR INTEREST. TO ACHIEVE THIS GENERAL OBJECTIVE, THE PROPOSED WORK WILL FOCUS ON THE FOLLOWING SPECIFIC TECHNICAL OBJECTIVES: FIRST, WE WILL IDENTIFY JAMMING REQUIREMENTS FOR FREQUENCY HOPPERS, I.E. VICTIM SIGNAL PARAMETERS WHICH AFFECT JAMMING REQUIREMENTS. SECOND, WE WILL DERIVE INNOVATIVE APPROACHES TO JAMMING FREQUENCY HOPPERS, INCLUDING WIDEBAND, NARROWBAND AND PARTIAL-BAND APPROACHES, AND IDENTIFY SUITABLE WAVEFORMS FOR USE WITH THESE APPROACHES, INCLUDING NOISE - AND CWTYPE WAVEFORMS. AND THIRD, WE WILL ANALYZE THE VARIOUS APPROACHES MATHEMATICALLY AND IN COMPUTER SIMULATION, AND PROVIDE THE GROUNDWORK FOR LABORATORY ANALYSIS.
