一种基于三坐标相控阵雷达的点迹凝聚方法

提出了一种基于三坐标相控阵雷达扫描方式和回波数据特性的点迹凝聚方法,根据目标回波数据的“图像性”数据结构,同时结合雷达工作参数和目标散射截面积等特性,采用经典图像处理算法——泛洪填充算法和三维质量中心算法,完成目标在距离、方位和俯仰三个维度上的点迹凝聚和检测输出。该算法能保证点迹动态实时输出,减小目标点迹输出延时,具有很大的工程实用价值。

Algorithm of Plots-Centroid Based on 3D Phased-Array Radars

An algorithm of plots-centroid based on 3D phased-array radars scanning and echo data structure is proposed. According to the image structure of target echo data, the radar operating parameter and the scattering area characteristic of the target, using the classical image processing flooding algorithm and center of the mass algorithm to achieve the target plots centroid and detection output in 3D dimensions of distance, azimuth and pitch. The algorithm can ensure the dynamic and real-time output of the plots, and reduce the delay of the output of the plots. It has great practical value in engineering.
