An Integrated Imaging and Target Detection Method for Spaceborne SAR

With the booming development of satellite technology, the era of big data in microwave remote sensing is coming. In recent years, SAR satellite constellations have been established and huge amounts of data have been accumulated. To discover intelligence information in SAR images and make rapid responses, one of the essential research fields is how to promptly image and automatically interpret. Generally, the imaging and target detection processes of spaceborne SAR are separated, which greatly constrained the real-time performance of target detection missions. Aiming at the above problems, an integrated technique of imaging and target detection for spaceborne SAR is carried out, which focuses on the data processing flow. Firstly, the imaging algorithm is improved and accelerated by the FPGA platform. Then the target detection model is lightweighted to improve the inference speed and facilitate portability. Finally, by optimizing resource allocation and pipelined processing, an integrated imaging and object detection method is proposed. The imaging efficiency and target detection speed have been improved. The proposed method lays a technical foundation for the imaging, detection, and fast response for spaceborne SAR.
