Radar receiver, in particular for a radar having an antenna with beam forming through computation, comprises essentially means (7) for matched filtering having a bandwidth B, means (12) for amplitude and phase detection, and means (8) for analog-to-digital conversion, and is such that said means for analog-to-digital conversion work on the intermediate- frequency signals, at a frequency much higher than said intermediate frequency. The receiver can be fully constructed in gallium arsenide technology, enabling use of optical fibre transmission of the detected data e.g. from an 'active array' to further processing circuits, thereby saving space. <IMAGE>
