Abstract: With the continuous advancement of technology, non-communication radar imaging is increasingly used in aerial observation and ground observation fields. This article conducts a systematic study on wireless orbit communication radar imaging technology and compensates for deviations in image quality accuracy through motion autofocus. The results show that the video-based backward projection algorithm proposed in this article is better than the RD algorithm and CBP algorithm in identifying large and small corner points. The feature fusion difference test of the rotated convolution unit was conducted on the ResNet18 and VGG16 neural networks and it was found that the recognition rate of the network architecture using the rotated convolution unit was significantly improved. The designed lightweight network based on rotational convolution units has an average recognition rate of 99.48% in the MSTAR data set.
