摘要
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.
Pulse compression radar is widely used in modern radar for its improvement of detection 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.
