LFM 脉冲压缩雷达的移频干扰技术研究

摘要

Pulse compression radar is widely used in modern radar for its improvement of de-tection range and range resolution .Its strong coupling phenomenon between detection range and the doppler shift , make it more vulnerable to interference than conventional radar .In this paper , the theoretical analysis and Matlab simulation of single false target frequency -shifting jamming , linear function frequency -shifting jamming and piecewise linear function frequency-shifting jamming were successively carried out .Simulation experiments showed the correctness and effectiveness of the theoretical analysis and provide theoretical guidance to resist pulse compression radar in engineering practice .%脉冲压缩雷达能够同时提高雷达的作用距离和距离分辨率，在现代雷达中被广泛采用。由于线性调频脉冲压缩雷达的距离－多普勒频移之间存在强耦合现象，使其比常规雷达更易受移频干扰。对单假目标移频干扰、线性函数移频干扰和分段线性函数移频干扰进行了理论分析和Matlab仿真验证，并对各种干扰进行比较和分析。仿真实验证明了理论分析的正确性和有效性，在工程实践上提供了对抗脉冲压缩雷达的理论指导。
