摘要:

为了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。该系统经过数次海上测控任务的检验,证明其方法科学有效、操作方便快捷、运行稳定可靠,达到了充分检验设备性能、提高任务准备效率的目的。

Abstract:

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, it is proved that the design method is scientific and effective, the operation is convenient and rapid, and the working is stable and reliable. With this system, the performance of equipments can be tested sufficiently and the efficiency of preparing tasks can also be improved.
