摘要
Abstract
With the rapid development of DRFM technology,and its outstanding deception and suppression effect,intermittent sampling and forwarding interference has been widely used in actual interference scenarios,which poses a serious threat to radar identification and detection.The non-uniform pattern of the sampling signal further expands the flexibility and deception of interference,and has a more obvious interference suppression effect on radar which is different from the conventional uniform intermittent interference.Through studying the generation mechanism of the in-pulse step frequency signal and non-uniform intermittent sampling and forwarding interference types in the radar transmission,this paper analyzes the time-frequency characteristics after pulse pressure.Finally,the degree of in-pulse agile step frequency interfered by non-uniform intermittent sampling is verified by simulation experiments.关键词
