跟踪雷达“指示引导”功能软件测试方法研究

Software testing method of indication and guidance functions of one tracking radar

在此研究用软件测试的方法对跟踪雷达"指示引导"功能进行测试。采用功能分解法对"指示引导"进行功能分解,分析典型空中高机动目标运动特性,设计了目标直线、圆周、俯冲等简单运动模型。运用模拟目标对雷达进行指示引导,以指示数据与雷达实际跟踪结果数据一次差结果作为功能是否合格的判据。给出了测试系统设计框图和运动模型实现程序,实际测试数据表明,有效地对雷达进行了跟踪引导,一定程度上解决了运用真实目标试验代价高昂的问题。

The software testing method of the indication and guidance functions of one tracking radar is studied. The func- tion decomposition method is adopted to decompose the indication and guidance functions, motion characteristics of typical high maneuvering target in the air are analyzed. The simple motion models of straight line, circle and subduction were designed. The simulation targets were used to indicate and guide the radar by taking the once-differenct results of indication data and actual ra- dar tracking data as a criterion that the functions are qualified nor not. The design block diagram of testing system and the imple- mentation procedures of motion model are given in this paper. The actual testing data show that, to a certain extent, the tra- cking guide for radar has solved the testing cost problem to use the real targets.
