摘要
针对多基地无源雷达中对单目标的定位问题,提出一种利用角度信息的加权最小二乘定位算法。设计了基于角度的目标定位模型,并根据不同的角度测量噪声设计了加权矩阵,进行了误差分析并推导了算法的Cramer-Rao界。仿真分析表明,本文算法优于同类算法,并且以3个接收站与一个外辐射源为例,给出了最佳位置配置建议。
To solve the problem of single target localization in multistatic passive radar,a weighted least square localization algorithm based on angle information is proposed.The target location model based on angle is designed,and the weighting matrix is designed according to different angle measurement noises.Then the error analysis is carried out and the Cramer-Rao bound of the algorithm is derived.The simulation results show that the proposed algorithm is superior to the same class algorithm,and the optimal location configuration is given by taking three receiving stations and one emitter.
