以组网干扰对抗现代雷达为研究背景,针对单脉冲雷达航迹欺骗问题,提出了基于干扰机组网主瓣干扰的航迹欺骗干扰技术。分析了单脉冲雷达干扰基本原理和航迹欺骗要点,给出了组网主瓣干扰航迹欺骗机理和实现过程。首先通过干扰信号传输路径和相位控制,构造两点源相干干扰条件,建立两台干扰机在雷达主瓣内形成可控欺骗点迹的基本模型。在此基础上,设计干扰机组网工作模式,采用组内协同和组间接力的方式对干扰模型进行扩展,形成持续性高逼真欺骗航迹。仿真结果证明了该技术的可行性和有效性。

Technique for track deception against monopulse radar based on netted mainlobe jamming

In the presence of the difficulty of monopulse radar track deception, a netted mainlobe jamming technique is proposed under the background of netted jamming against modernradar. The course and process of the jamming is put forward based on the analysis of the basic theory of monopulse radar jamming and the key point of track deception. Firstly,the coherent jamming is constructed by the transmission path and the phase control of the jamming signal, and the fundamental model of the generation of phantom dots in radarmainlobe is built. Furthermore, the jammer net working mode is designed which emphasizes the cooperation in the jammer group and relay between the jammer groups. Thus, thejamming model is improved on integrating the phantom dots into a full track for long time high-reality deception. Simulation results verify the feasibility and validity of theproposed algorithm.
