摘　　要：针对解算海面贴近目标时存在的问题,基于常规对海雷达处理中距离维聚心和方位维波束相关算法,文中进行了优化改进,提出了一种距离维聚心的改进方法。该算法以海面目标的距离维、方位维的特征分析为基础,通过方位维分段聚心的方法对贴近目标进行区分。实测数据仿真表明,该算法可明显提高海面贴近目标的检测和分辨能力。In this paper,based on analyzing the calculation of the range-dimensional gather and beam correlation of azimuth-dimensional,a new calculation of range-dimensional gather is proposed to overcome the disadvantages of detecting the closed sea targets.This calculation is based on the characteristic of range-dimensional and azimuth-dimensional of sea targets,and detect targets through detached range-dimensional gather.This calculation can improve the detection capability and measure accuracy for the closed targets obviously through the simulation of measured data.
