中文摘要:为满足船载统一测控系统沟通无线偏馈射频链路进行遥测误码率测试的要求,进一步构建系统联调联试的动态射频信号环境,设计了船载测控雷达偏馈信号动态控制系统。通过系统监控台手动或自动远程控制位于天线背部中心体的数控衰减器,可实现雷达天线在对冷空的情况下接收偏馈射频信号幅度的变化,也可实现船载测控雷达系统联调过程中模拟目标动态变化情况,进而分析对系统跟踪性能的影响。该系统在数十次海上卫星测控任务准备过程中得以有效使用,检验了设备的工作性能,提高了任务准备的效率。
英文摘要:To meet the requirement of bit error probability test of telemetry when shipboard TT&C system aligns the offset dipole, and make a further step in building a dynamic radio frequency signal environment for joint debugging and testing, a dynamic control system is designed in offset dipole on shipboard TT&C radar system. The numerical control attenuator can be controlled by manual or automatic at SMCU, which located in the long-distance antenna central body. It can achieve that amplitude change of RF signal in offset dipole received by radar antenna pointing to the sky, and offer a new way to simulate the flight target dynamic signal in joint debugging,which help to analysis effects of the tracking performance in the system. Since the system has been verified in maritime track and control tasks several times, it is proved that the performance of equipments can be tested sufficiently and the efficiency of preparing tasks can also be improved.
