ABSTRACT:
A technique for processing the IF portion of a radar return signal in order o produce a continuous voltage output which voltage is proportional to the instantaneous frequency of the received signal. The technique employs an amplitude limiter and a wideband discriminator comprised of a delay line and phase detector followed by a video amplifier for processing the desired output signal. The output signal is indicative of velocity of precipitation in the radar target range. This information may be employed to detect and measure the degree and intensity of precipitation fall velocities, winds within a storm and other velocity dependent characteristics.
