Abstract
A radar system and a method of operating a radar system. The radar system comprises a transmitter-receiver subsystem to transmit a series of electromagnetic pulses, to scan those pulses across an area of interest, and to receive echoes of the pulses. The radar pulses may be transmitted at a multitude of frequencies, each of which is in one of a multitude of channels. The radar system further includes a channel selection subsystem, first, to measure or sample the electromagnetic interference received by the transmitter-receiver subsystem in each of the channels of the radar system during each of at least selected scans of the radar pulses across the area of interest, and second, on the basis of those interferences measurements, to select automatically a channel of the radar system to transmit the radar pulses and to generate a signal identifying that channel. The transmitter-receiver subsystem includes a channel selector for receiving this signal from the channel selection subsystem, and in response to that signal, for selecting a frequency in the selected channel to transmit the radar pulses the next time those pulses are scanned across the area of interest.
