Abstract：A miniaturized high resolution W-band SAR system developed by the Institute of Electronics of the Chinese Academy of Sciences is introduced. The parameters, architecture of the system and signal processing method are described in detail. The solutions of key problems which include non-linearities error calibration, high-accuracy motion compensation and high-isolation transceiver system design are proposed. The W-band radar system is tested by airborne experiment and the results show the effectiveness of the presented system.
