一、引言在几部收信机共用一付天线进行通信的场合下,任何一架收信机的本机振荡器在“天线”端所泄漏出来的电能必然很容易传输到其他收信机中,因此引起通信中的相互干扰.虽然目前都采用天线共用器,但在收信机泄漏电能很大时,仍不能很好地解决问题,同时在收信机少时,也不经济.另外,在军用通信中,当甲方进行通信时,乙方可以用测向器来搜索甲方收信机 I. INTRODUCTION In the situation where several receivers share the same antenna for communication, the energy leaked by the local oscillator of any one receiver must be easily transmitted to other receivers Machine, thus causing mutual interference in the communication.Although the use of antenna duplexer, but the receiver leakage power is very large, the problem is still not well solved, while the receiver is less, it is not economical. , In military communications, when Party A communicates, Party B can use direction finder to search Party A’s receiver
