On deception jamming for countering LFM radar based on periodic 0-π phase modulation

Abstract Coherent jamming technology is one of the most important development trends in the modern radar countermeasures. This study presents a method capable of generating a series of deceptive coherent false targets for countering linear frequency modulation (LFM) radar based on periodic 0-π phase modulation. Utilizing the structure of digital radio frequency memory (DRFM), we impose phase modulation onto the intercepted radar signal and retransmit it to the victim radar. The jamming signal model is developed and its characteristics are analyzed in detail. An investigation has been carried out to determine the matched filter properties of the jamming signal. The expressions of some main parameters are deduced step by step. Theoretical analysis and simulation results prove that by flexibly adjusting the phase modulation parameters, different deception jamming effects will be obtained. The proposed method provides an idea for the coherent jamming signal design.
