Radar Duplexer Leakage Spike Suppressor

US Patent:
5134414, Jul 28, 1992
Filed:
Mar 20, 1991
Appl. No.:
7/672464
Inventors:
Joseph G. Ditullio - Woburn MA
Peter D. Dolan - Wakefield MA
Edward H. Shively - Raymond ME
William R. Romaine - Acton MA
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
G01S 7285
US Classification:
342198
Abstract:
A method and apparatus for suppressing leakage spikes in a radar duplexer. A flash of radiant energy is triggered immediately prior to sending a radar pulse so as to ionize the gases in a duplexer tube before the leading edge of the radar pulse reaches the tube. The spike suppressor includes an radiant energy source which attaches to the radar duplexer so that the source shines into the duplexer tube. A pulse generator is provided for activating the source in response to a trigger signal.
