Mechanism and Preliminary Experiments of a L-Band Synthetic Aperture Microwave Radiometer

In this paper, prototype of a two-channel L-band interferometric synthetic aperture microwave radiometer, which is infect a two-element microwave interferometer, is designed and developed. The correlation experiment is conducted. Results of the experiment show that phase difference can be exactly retrieved with the complex correlator, which can be a core component of a synthetic aperture radiometer.
