【摘要】: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。
[Abstract]:In view of the complex and changeable space environment, a design method of fine point trace processing algorithm based on the primary radar system of ATC is proposed. The point trace processing algorithm mainly completes the initial echo processing, the point trace condensation processing and the point trace filter processing of the primary radar. After the pulse compression MTD filter and CFAR detection, the effective data parameters of the echo are extracted, and the primary point trace data is sent to the terminal for display. At the same time, the interference echo is eliminated, and the fixed echo is eliminated. Other echo data parameters caused by slow moving echo and low mass grade echo. The effectiveness of this algorithm in radar system engineering is proved by the application of some key techniques in the primary radar of ATC.
