摘　　要：火星环绕器配备了3个对地接收通道,4个对地发射通道;虽然收发天线在X频段工作频点不同,但是在上行通道灵敏度高达-156dBm的情况下,100W发射信号仍不可避免地耦合到接收通道中,对上行遥控产生影响。本文对火星环绕器多通道天线情况下的收发隔离,通过5种途径进行了隔离设计,解决了高灵敏接收、大功率发射情况下的多通道收发隔离度难题。Mars Surrounder is equipped with three ground receiving channels and four ground transmitting channels;Although the receiving and transmitting antennas work at different frequencies in X-band,but in the case of uplink channel sensitivity up to-156dBm,the 100W transmitting signal is still inevitably coupled to the receiving channel,which has an impact on the uplink remote control.In this paper,the isolation of the Mars Surrounder multi-channel antenna case,through five ways of isolation design,to solve the problem of multi-channel transmission and reception isolation degree in the case of highly sensitive reception and high-power transmission.
