ABSTRACT:
A weather radar incorporating a sensitivity time control modifying circuit for adaptively increasing the gain of the IF amplifier as a function of precipitation rate; thereby increasing the range of the radar through the precipitation and identifying on the display those regions in which the radar might otherwise inaccurately indicate the precipitation rate. Reflections from the precipitation are received by the radar antenna coupled to a mixer wherefrom an IF signal is coupled to the IF amplifier wherein it is amplified in accordance with a gain that is determined by the modified sensitivity time control signal.
