多目标试验机试飞态势监视系统的设计与实现

摘要

为解决当前型号任务中因环境和飞机大机动等因素导致测试目标丢失后的重新搜索和跟踪问题,对实时遥测系统的结构和原理进行了研究,设计并实现了具有多目标监视功能的试验机试飞态势监控系统;系统通过引入二次雷达数据,解决了由于 PCM 信号中断后,不能及时掌握试验机态势信息的问题;另外,通过计算飞机相对遥测天线的相对角度,辅助遥测天线跟踪测试目标;使用结果表明,系统对保障重点型号的试飞安全起到了重要的作用.%In order to solve the problem of re -searching and tracking after the loss of test target due to environment and aircraft maneu-ver in the current model task,we study the structure and principle of real -time telemetry system,and design and develop the system for mo-nitoring situation of multi - target test planes.By introducing the secondary radar data,the system can solve the problem that the situation information of test plane cannot be grasped in time after the PCM signal interruption.In addition,by calculating the relative angle of the air-craft relative to the telemetry antenna,the auxiliary telemetry antenna tracks the test target.The results show that the system plays an im-portant role in ensuring the flight safety of key models.
