N2 - Multistatic SAR based on UAV swarm can reduce synthetic aperture time and increase the imaging frame rate while maintaining high image resolusion, thus it is of great promising prospect. Due to the lack of efficient and high precision imaging methods, the performance of UAV swarm SAR is not fully developed. Therefore the imaging method suitable for UAV swarm SAR is studied in this paper. Compared with frequency domain imaging techniques, time domain imaging method is more appropriate for UAV swarm SAR with complex trajectories. But the heavy computational burden is a problem. Thus this paper proposes a fast imaging method based on spectrum fusion for high frame rate UAV swarm SAR. In the method, each bistatic pair in UAV swarm SAR is split into several sub-pairs to generate coarse angular resolution images and the fusion of images is realized through spectrum fusion, which obtains the imaging result of UAV swarm SAR. Experiment is carried out to verify the effectiveness of the proposed method.
