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。
脈遲壓縮雷達能夠同時提高雷達的作用距離和距離分辨率,在現代雷達中被廣汎採用。由于線性調頻脈遲壓縮雷達的距離-多普勒頻移之間存在彊耦閤現象,使其比常規雷達更易受移頻榦擾。對單假目標移頻榦擾、線性函數移頻榦擾和分段線性函數移頻榦擾進行瞭理論分析和Matlab倣真驗證,併對各種榦擾進行比較和分析。倣真實驗證明瞭理論分析的正確性和有效性,在工程實踐上提供瞭對抗脈遲壓縮雷達的理論指導。

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 .
