  • Radar duplexer leakage spike suppressor
    Patent number: 5134414
    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.
