摘要
该文介绍了中国科学院电子学研究所研制的一套高分辨率W波段SAR系统,对系统的指标、组成、实现方案以及数据处理方法进行了描述,提出了非线性系统误差校正、高精度运动补偿、高隔离度收发系统设计等关键问题的解决方案。通过机载飞行实验,验证了W波段SAR系统的有效性。
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.
