某地面遥测接收站过顶跟踪改进方法

Improved Method of Passing Zenith Tracing for Certain Ground Tele-Metering Receive Station

针对俯仰—方位型跟踪系统在飞机过顶情况下无法进行平稳跟踪甚至丢失这一问题,根据俯仰—方位型测控通信设备的跟踪特点,提出解决目标过顶跟踪的实用方案。深入分析俯仰—方位型跟踪系统天顶盲区的形成机理,讨论当目标过顶时方位角速度的影响。对解决该问题所涉及的相关技术进行研究,总结出跟踪解决天顶盲区的方案,并对方案中程序引导方法对过顶目标跟踪进行仿真实验。结果表明:该方法使系统过顶后能继续捕获跟踪目标,对保持试验任务的顺利进行具有一定的现实意义。

Aiming at the pitching and azimuth tracking system over the top case in aircraft cannot smooth tracking or even lost this problem, according to the characteristics of pitch and azimuth tracking control of communication equipment, put forward to solve the practical scheme for tracking target over the top. In-depth analysis of the formation mechanism of pitch and azimuth tracking system the zenith blind spot, discuss when the effect of target over the top when the azimuth velocity. Research the technology involved in solving the problem, summarizes the tracking solution zenith blind zone scheme, and the scheme of program guide methods over the top target tracking simulation experiment. The results show that, this method makes the system overhead can continue to capture and track the target, has the certain practical significance to keep the test task smoothly.
