摘　　要：文中论证了基于通用仪表的复杂电磁环境构建的设计及实现过程,并提出了一种幅相误差校准的方法,给出了实际校正网络框图。试验结果表明,存在幅相误差的信号经该网络校正后,镜频和本振抑制达到了40 dB以上,可满足工程上的需求,能更加真实地模拟出实际电磁环境信号。This paper demonstrate a realization of the process and the design of complex electromagnetic environment based on uni- versal instrument, and proposes a error correction method of the amplitude-phase, and gives the block diagram of ：correction net- work. The test results shows that the power of the main signal to the the mirror frequency and LO suppression can be up to 40 dB when the signal with amplitued-phase error is corrected by the network. Therefore, it can be widely used for the engineering. It haves more ability of simulating the actual electromagnetic signals.
