Abstract

The first phased array radar dedicated to weather observation and analysis is now instrumented with eight simultaneous digital receivers. The addition of these additional channels will enable the use of advanced signal processing to improve signal/clutter in an adaptive mode. Elimination of strone point and ground clutter returns from the low-level, volumetrically-distributed weather cell returns is a new application of adaptive processing. The NSF funded 8-channel receiver has been added to the National Weather Radar Testbed (NWRT) system in Norman, Oklahoma, to enable operation as a multi-function and/or adaptive processing system. Herein, we describe the system concept, system installation and early results from fielded weather data returns.
