针对场面监视雷达的应用需求,首先对地面民航机的运动场景和状态进行分析与仿真,对于机场目标运动模型多样、受环境影响大的情况,研究基于检测前跟踪算法的场监雷达数据处理算法;并将机场数字地图信息和目标数据库融入场内目标的跟踪过程,以提高雷达对不同运动状态目标的跟踪性能;同时,对异常情况及时告警,确保机场飞行安全;最后给出了仿真数据及某机场实测数据的处理结果,验证算法有效性。

Focusing on the demand of surface movement radar, first of all, different motion states of civil aircrafts on airport are analyzed and simulated. Then the data processing algorithm of SMR based on the TBD(Track Before Detect) is introduced briefly. The key technologies, the processing in special areas and the design of confidence coefficient, are expatiated. the map information of airport and target database are also proposed to use on the aircrafts tracking, in order to improve tracking performance and give an alarm in time when accident happened. Finally, simulation results and actual measurement results are analyzed, and improve the algorithm validity.
