摘要
间歇采样转发式干扰与雷达发射信号相参,可以获得部分脉压增益,具有极强的干扰效果,亟需有效的干扰先验知识对抗。针对该问题,本文根据间歇采样转发干扰脉冲压缩后的结果,构造出含有加窗向量的非线性整数优化模型,将参数估计问题转化为向量估计问题,然后利用交替方向乘子法(Alternating Direction Method of Multipliers,ADMM)将非线性整数优化模型分解为整数归整模型和连续模型,求解出加窗向量,实现切片宽度和数量的估计。最后计算机仿真验证了该方法的有效性。
Interrupted sampling repeater jamming is coherent with radar transmitting signal,which can obtain partial pulse compression gain and has strong jamming effect.Therefore,effective prior knowledge of jamming is urgently needed.To solve this problem,this paper constructs a nonlinear integer optimization model with windowed vectors according to the results of interrupted sampling repeater jamming pulse compression.The parameter estimation problem is transformed into a vector estimation problem,and then the nonlinear integer optimization model is decomposed into integer model and continuous model by the alternating direction method of multipliers(ADMM)to estimate the width and number of slices.Finally,computer simulation results show the effectiveness of the method.
