New Antivelocity Deception Jamming Technique using Pulses with Adaptive Initial Phases
TLDR
An effective electronic counter-countermeasures (ECCM) technique for a moving target indication/pulsed Doppler (MTI/PD) radar system against velocity deception jamming and a novel radar signaling strategy based on variations of the initial phases of the transmitted pulses in pulse repetition interval (PRI) domain are proposed.Abstract:
An effective electronic counter-countermeasures (ECCM) technique for a moving target indication/pulsed Doppler (MTI/PD) radar system against velocity deception jamming is proposed. A novel radar signaling strategy is outlined based on variations of the initial phases of the transmitted pulses in pulse repetition interval (PRI) domain. It makes the Doppler spectrum of the false targets, created by a digital radio frequency memory (DRFM) repeat-back jammer, form a notch around the Doppler frequency of the true one. The penalty function and corresponding algorithm for designing adaptive initial phases are given. We also present an approach of the multi-channel matched filter processing to estimate the manner, by which a DRFM repeat jammer operates, and the parameters of the false targets. The working flow of an MTI/PD radar for countering velocity deception jamming is investigated. Simulation results show the effectiveness of the above methods.read more
