针对无线电经纬仪实装训练时探空仪、探空气球、制氢原料等耗材消耗大，性能检测设备缺乏，抗干扰训练难以展开等问题，设计了无线电经纬仪探测信号生成系统；采用数字信号处理技术、多路调制技术实现了高空气象探测探空信号的模拟，采用数字移相技术实现了测角误差信号的模拟，采用DDS信号生成技术实现了干扰信号的产生；可在不施放探空气球的情况下为无线电经纬仪提供模拟探测信号和干扰信号，即能节约训练经费又能为性能检测和复杂电磁环境生成提供信号源。

Aims to solve the Problems that have occurred in the radiotheodolite mounting training,such as large consumPtion of radiosonde,ballons and hydrogen materials,lack of Performance testing equiPment, interference training difficulties,this PaPer designs a sounding signal generation system,which can achieve the simulation for high﹣altitude meteorological sounding signals by digital signal Processing technology and multiPlexer technology,the simulation for angle measurement error signal by digital Phase shift technology, and the generation of interference signal by DDS signal generation technology. It can Provide an analog de﹣tection signal and interference signal for the radiotheodolite without balloons,which can not only save training funds,but also Provide the signal source for Performance testing and the generation of comPlex e﹣lectromagnetic environment.
