摘要:

主瓣掩护式干扰会导致单脉冲雷达的探测、跟踪、识别性能严重下降, 如何在该场景下进行目标角度估计是单脉冲雷达面临的经典问题。为解决该问题, 提出了一种单脉冲雷达目标角度估计算法, 该算法运用残差矩阵Frobenius-范数(以下简称残差矩阵F-范数)最小化准则提取目标回波及干扰信号并估计其来向。仿真结果表明, 该算法相比主瓣干扰对消(mainlobe jamming cancellation, MLC)算法, 测角精度更高, 稳定性更强。

关键词: 主瓣干扰, 角度估计, 主瓣对消

Abstract:

The detection, tracking and recognition performance of monopulse radar will be severely degraded due to the mainlobe cover jamming. How to estimate the target angle in this scene is a classic problem faced by monopulse radar. In order to solve this problem, a target angle estimation algorithm for monopulse radar is proposed. The algorithm uses residual matrix F-norm minimization criterion to extract target echo signal and estimate the direction of the target echo and jamming. The simulation results show that the proposed algorithm is more accurate and stable than the mainlobe jamming cancellation (MJC) algorithm.

Key words: mainlobe jamming, angle estimation, mainlobe cancellation
