ABSTRACT:
This radar receiver, in particular for a radar having an antenna with beam forming through computation, comprises essentially means for matched filtering having a bandwidth B, means for amplitude and phase detection, and means 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.
