Radar detection of turbulence in precipitation

摘要

A technique for processing the IF portion of a radar return signal in order to provide the remote detection and measurement of atmospheric turbulence occurring within precipitation. The technique employs an amplitude limiter, a wideband discriminator and a video amplifier to provide real time measurement of the precipitation velocity. A velocity comparison at various radar ranges is made to provide an indication of the turbulence. The analog circuit employed to make this measurement operates with high speed and is capable of being used with any pulsed (coherent or non-coherent) weather radar.
