摘要
线性函数移频干扰可以对线性调频脉冲压缩雷达形成有效的压制性干扰,改变载频和调频斜率均无法有效对抗线性函数移频干扰。通过分析线性函数移频干扰对线性调频脉冲压缩雷达的干扰效果和原理,提出了基于FRFT的抗线性函数移频干扰算法,从理论上分析了该算法的可行性,最后通过仿真验证了该算法的正确性和可行性。
A linear frequency shifting jamming can effectively form blanket jamming on LFM pulse- compression radar. Carrier frequency and chirp rate changes are not effective against the linear frequency-shifting jamming. By analyzing the interference effect and principle of the liner frequency-shifting iamming on the LFM pulse-compression radar, an algorithm against linear frequency-shifting jamming based on FRFT is put forward and the feasibility of the algorithm is analyzed in theory. Finally the correctness and feasibility of the algorithm is verified by simulation.
