This can be done by directly coupling the device to the unit via the interfaces 58 and 80 or use can be made of another technique such as a short range radiofrequency or infrared link.
Isolation of the T/R switch must be considered when the high power transmitter is connected to the low power radiofrequencyunit by T/R switch as the radar antennas are reciprocal.
雷达天线往往收发共用,通过收发开关连接高功率发射单元和低功率射频单元要考虑收发开关的隔离度问题。
