Abstract�� The imaging principle, system structure and characteristics, calibration approach, several imaging experiments and imaging results of 2-dimensional synthetic aperture microwave radiometer BHU-2D (BeiHang University 2-Dimensional) were presented. BHU-2D operates at 8��mm wave band and has 10 receiving channels. The antenna array of BHU-2D is T-shape; receivers- configuration is super heterodyne and has two down converters. I/Q demodulation and correlation of BHU-2D were carried out with digital method and by software; the channel unbalance, correlation bias and aliasing errors were calibrated with radiated point source and background drop inversion algorithm. At present, BHU-2D was accomplished and has been undergoing testing and imaging experiments, and the radiometric brightness distribution images of man-made scenes and the person in lab were obtained.
