Abstract :
LX-band Full Polarization Aperture Synthesis Microwave Radiometer (FPASMR) is a 2-D aperture synthesis radiometer which can measure the sea salinity and soil moisture. As a key component of FPASMR, the digital correlator has been introduced in this paper from three abstract: the system design, the hardware design and the test results of the demonstrator. The results demonstrate that the digital correlator referred in this paper can ensure the realtime signal sampling and processing of 140 ADC channels which meet the practical requirements.
