It is quite important for the radar observer and all users of radar data to be familiar with detection capabilities of the various radars used throughout the National Weather Service. It is also important that studies be made of radar data in hopes of finding possible ways of better utilization of raw radar data. This study was made to determine how accurately moderate or greater precipitation can be detected utilizing returns which break through Circular Polarization (CP) and Moving Target Indicator (MTI) circuit of Federal Aviation Administration Air Route Traffic Control Center (FAA/ARTCC) radars. We also hope to give users an idea of what degree of confidence they can have in reports of moderate or greater precipitation areas.
