根据三坐标雷达波束扫描和波束空间分布的特点,本文采用“距离上峰值搜索,方位和俯仰上使用质量中心法”作为目标点迹凝聚方法,设计了三坐标雷达点迹凝聚算法,并在该雷达硬件平台上实现.试验表明,该方法不仅降低了弱小目标被滤除的概率,还有效的减小了点迹在距离、方位和俯仰上的分裂,为后续的航迹处理提供了一个可靠的基础.此外,此算法可以实现递推运算,占用存储空间少,易于工程实现.“,”According to the characteristics of the beam scanning and beam distribution in space of 3-D radar, a plots centriod algorithm of the peak-searching in range and the centfiod at azimuth and pitch is designed and applied for radar. The result has shown that the use of algorithm not only reduces the probability that weak targets is filtered out, but decreases the split of the plots in range and at azimuth and pitch so as to provide a reliable basis for further track processing. The algorithm is easily implemented in engineering application because it is a recursive algorithm and takes less memory.
