Isolation of the T/R switch must be considered when the high power transmitter is connected to the low power radio frequency unit by T/R switch as the radar antennas are reciprocal.

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 radio frequency or infrared link.

Equipment for implementing intelligent antenna includes: array diversity antenna, radio frequency channels, beam forming unit, baseband processing MODEM and beam controller.
