摘　　要：通常采用对前桅方式接收转发机的射频信号进行相关指标测试或系统无线联试,此种方式需要多岗位配合且USB固态功放发射功率有可能导致S频段导航雷达受到干扰;通过研究数控衰减器在单片机控制系统中的应用,设计了船载USB系统偏馈信号动态控制系统,可实现雷达天线在对冷空的情况下接收静态或动态变化的偏馈射频信号,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。Usually, it can receive the RF signal transmitted by converter to achieve certain testing and wireless joint debugging for anten- na pointing to the fore mast. It needs to cooperation for multi-- system and causes the interference for S-- band navigation radar by USB solid state power amplifier. By the study on MCU control system with numerical control attenuator, the paper designs a dynamic control system in offset dipole on shipboard USB system. It can achieve static or dynamic RF signals in offset dipole by radar antenna pointing to the sky, 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 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.
