ABSTRACT:
A radar warning receiver for detecting and analyzing radar signals comprises a plurality of RF heads each tuned to a predetermined frequency band and connected to an antenna covering a preselected sector of reception of radar signals. Each of the heads includes a frequency converter converting the received signals to a common frequency base-band and producing an output signal in the base-band corresponding to the signal received by its antenna. The radar receiver also includes a central receiver unit receiving the signals from the RF heads, the central receiver unit comprising a plurality of channels, one of each RF head, for receiving and processing the signals from the respective head; and mode selector means for selectively switching the central receiver unit to operate according to: (a) an Acquisition Mode, wherein the plurality of channels are connected to cover contiguous sub-bands of the base-band; or (b) an Analysis Mode, wherein the plurality of channels are connected in parallel to cover the same sub-band of the base-band.
