摘要：

A small-size and highly-integrated real-time processing system for small UAV borne SAR is presented in the paper. The system collects and processes radar echo data in real time, efficiently compresses the raw data without significantly compromising imaging quality, and transmits the compressed data to the ground center for fine imaging. Compared to existing SAR systems, this paper offers advantages of smaller size, lighter weight, and flexible application. A prototype preprocessing unit was developed, measuring 7x7x2cm(3) and weighing 200g, with the capability of seamless three-dimensional integration with the antenna and RF system. A UAV-borne flight imaging test validated the real-time imaging effectiveness of this system.
