The analog complex correlator used in aperture synthesis radiometers is easy to be affected by many complicated factors,for example ambient temperature,signal crosstalk and so on. These factors result in correlator offset value change with time,which will significantly impact the performance of aperture synthesis radiometers. Real-time elimination of the effect of complex correlator offset value is the difficult and key point in the design of aperture synthesis radiometers. In this paper,a calibration metho...
