Mathematic principles of interrupted-sampling repeater jamming (ISRJ). (English) Zbl 1218.94025

Summary: Coherent jamming is one of the important trends in modern radar electronic warfare. High-speed sampling of wideband radio frequency (RF) signals and high isolation of two receive-transmit antennas are key technologies for the realization of coherent jamming. However, these technologies present significant challenges to engineering application. In this paper, a novel repeater jamming based on interrupted sampling technique is presented. For a jammer with a receive-transmit time-sharing antenna, a radar signal is sampled with a low rate by the jammer. Then, a train of false targets will be achieved after the jamming signal feed the matched filter of a pulse compression radar. For the case of the linear frequency modulated (LFM) pulse compression radars, a mathematical principle of the interrupted-sampling repeater jamming is developed, and then the efficiency of the jamming is described and stated as expressions of key parameters which are also beneficial to the jamming design for other coherent radars.
