摘要：
This paper presents the description and performance tests of an L-band microwave radiometer with Digital Beamforming (DBF), developed for the Passive Advanced Unit (PAU) for ocean monitoring project. PAU is an instrument that combines, in a single receiver and without time multiplexing, a microwave radiometer at L-band (PAU-RAD) and a GPS-reflectometer (PAU-GNSS-R). This paper focuses on the PAU-RAD beamformer's first results, analyzing the hardware and software required for the developed prototype. Finally, it discusses the first results measured in the Universitat PolitScnica de Catalunya (UPC) anechoic chamber.
