针对高分辨雷达在跟踪扩展目标时出现多散射点的问题，提出了一种基于联合概率加权的雷达目标点迹处理方法。首先，对信号检测出的多散射点构建其残差变量，根据判别准则进行目标点迹配对处理，剔除异常散射点；然后，同时考虑散射点位置和回波幅度信息，计算联合概率的权值，目标多散射点经概率加权融合后估计得到散射中心。仿真分析表明，该方法在高分辨雷达扩展目标点迹处理中能有效抑制杂波的干扰，目标点迹精度在距离、方位和俯仰上分别提高了20.63%、47.51%和41.03%，同时具有很好的可靠性，满足工程应用的需求。

To solve the problem of multi-scattering dots during high resolution radar tracking extended tar-gets, a radar target dot processing method is proposed based on joint probabilistic weighting technique. Firstly,remained variables of the detected multi-scattering dots are constructed. According to judgment rule for target dot partnership processing, abnormity scattering dots are eliminated. And then,scattering dot position and echo amplitude are considered to calculate the joint probabilistic weighted value and scattering center is estimated by target multi-scattering dots weighted fusion. Simulation results show that the method can efficiently restrain clutter in high resolution radar tracking extended target dot processing, and the esti-mation precision is improved 20. 63%,47. 51% and 41. 03% in range,azimuth and pitch,respectively. The method is reliable and meets engineering requirement.
