Design and Implementation of Synchronous Pulse Jamming in the Simulation of Radar Working Environment

雷达环境仿真系统是为检测雷达设备的抗干扰能力而设计的,同步脉冲干扰是采用假目标和信息,产生与雷达工作信号具有相参性和同步性的干扰信号,作用于雷达的目标检测系统、跟踪系统和数据处理系统,有效地破坏雷达对目标的检测、跟踪。该文从同步脉冲干扰的基本原理出发,阐明在雷达工作环境仿真系统中距离拖引、速度拖引、虚假目标等同步脉冲干扰的设计和实施过程;并针对工作在搜索和跟踪交替模式下的相控阵雷达提出自适应综合干扰方式;最后分析并总结了系统仿真时为有效实施同步脉冲干扰应注意的事项。

The simulation system of radar environment is designed to test the anti -jamming capability of radar. To disturb the target checking and tracking system of radar efficiently, synchronous pulse jamming signals which are correlated and synchronized with radar signals are produced by using false target and false information to act on the target checking system and tracking system and data processing system of radar. Based on the fundamental principle of synchronous pulse jamming, this paper illuminates the design and implementing process of synchronous pulse jamming such as range gate pull off jamming , velocity gate pull off jamming , dummy target jamming and so on. A self - adapting synthetically jamming mode is put forward aimed at the phased array radar which works alternately between searching mode and tracking mode. In the end of this paper, the key points are analysed in the implementation of synchronous pulse jamming.
