航管一次雷达精细化点迹处理设计与实现

Design and Implementation of Fine Plot Processing in Air Traffic Control Radar

针对复杂多变的空间环境,提出了一种基于航管一次雷达体制下精细化点迹处理算法的设计方法。该点迹处理算法主要完成一次雷达的初始回波处理、点迹凝聚处理和点迹滤波处理。提取经过脉冲压缩、MTD滤波、恒虚警检测(CFAR)后的回波有效数据参数,形成一次点迹数据送给终端显示,同时剔除由干扰回波、固定回波、慢动回波和低质量等级回波等引起的其他回波数据参数。该算法中的一些关键技术在航管一次雷达中的应用效果证明了其在雷达系统工程中的有效性。

An algorithm of plot agglomeration based on the primary surveillance radar（PSR） for air traf- fic control is proposed on the complicated space environment. The algorithm achieves original echo process- ing, plot agglomeration and filtering. By distilling the effective parameters which are processed through pulse compression, MTD filter and CFAR, the data is sent to the terminal display. Simultaneously, the other ech- oes are eliminated, such as jamming echo, fixed echo, slow moving echo, and low-quality level echo. The validity of the algorithm is proved in a PSR.
