摘要通过计算与分析发现,引起网调端收信机干扰的信号是两个发信信号相互作用所形成的三阶互调信号,随后的实验也证实了计算与分析的结果。还分析了电压驻波比增大的原因,并提出了相应的解决办法。 This paper presents that the signal which arouses the interference of the receiver located in Central China Electric Dispatching Bureau is the three_stage inter_modulation signal being formed by two transmitting signals through the method of calculation. Then the experiments improve that the calculation is right. And finally the paper analyses the cause of the increasing of standing wave ratio and the relavent solution.
