Intermittent sampling and forwarding is a new type of interference pattern, which is suitable for matching filtered pulse pressure radar in principle. In this paper, a method of using this interference pattern to realize the wideband radar jamming of the deskewing processing system is presented. After analyzing the basic principle of interfering signals after the radar de-skew processing, the time-domain characteristics and frequency-domain characteristics of the false targets are described. The amplitude characteristics of the false targets are analyzed, and the requirements on the jammer power Focusing on the aliasing phenomenon caused by interference delay, this paper analyzes the spatial distribution of false targets and the spatial distribution of false targets, and points out the key factors that determine the spatial distribution of false targets. The corresponding simulation experiments and analyzes The simulation results.The research results in this paper are instructive for the design and use of the intermittent sampling-and-forwarding jammer.
