Abstract
A radar system with digitized video having a digital interference rejection circuit for eliminating spiral interference caused by nearby radar transmitters operating in the same frequency band. Video signals from each sweep are stored in a random access memory. A comparison is made between adjacent range cells in the present 'live' video signal and the video signal from the previous sweep. The output video signal to the display device is inhibited should the comparison indicate the presence of interference.
