Method of Monitoring Microwave Emissions from the Environment Using a Radar System

摘要

A radar system includes a transmitter 20 operable to transmit microwave signals within a given range of frequencies and a receiver 50 operable to receive reflected or backscattered signals within the said given range of frequencies. The system includes further means for effecting radiometric monitoring of signals received by the receiver at frequencies which extend beyond the said given range of frequencies transmitted by the transmitter. A second aspect of the invention provides a method of monitoring microwave emissions from the environment by signals received by a receiver of a radar system by acting to exclude the range of frequencies transmitted by the transmitter from the range of received frequencies propagated through the radar waveguide 25 and antenna 30 subsystems, and performing radiometric analysis thereon.
