Platform echo and cross‐eye jamming against active‐passive composite monopulse radars
IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2134-2143, November 2024.In this paper, platform echo and cross‐eye jamming signals are jointly considered to analyse the jamming performance on active‐passive composite monopulse radars (APCMR). In order to ensure the jamming performance on both active and passive radars in APCMR, a guideline for the setting of jammer parameters is proposed based on numerical simulations ...
