VxWorks平台下的米波雷达点迹凝聚方法研究

通过对采集的实际数据分析提出了用质心法求方位能够提高米波雷达的跟踪性能，并针对米波雷达回波距离精度差、方位分裂比较严重的特点，以VxWorks操作系统为开发平台，充分利用雷达观测到的目标原始回波参数信息，提出了一种在多个距离量化单元以及相邻方位扇区之间进行距离与方位上逐次归并的点迹凝聚算法——回波渗透法。试验表明，该方法不仅降低了弱小目标被滤除的概率，还有效地减小了点迹在距离与方位上的分裂，为后续的航迹处理提供了一个可靠的基础。

A Plot Clotting Approach of Meter Wave Radar Based on VxWorks

Based on analyzing the collected data, we present that the tracking ability of meter wave radar can be improved by use of the centroid algorithm to find azimuth. For the limitation of low range precision and azimuth split, a new plot clotting approach which is based on VxWorks and fully uses the observed target parameters is proposed. It is called as wave penetration algorithm. The algorithm makes clotting by combining plots one by one between several adjacent range cells and azimuth sectors. This approach not only lowers the probability of removing the small target, but also reduces the split of plot in range and azimuth. It makes great importance to track processing.
