  • Abstract
    Pulse repetition frequency (PRF) redundancy exists in near space slow speed SAR due to slow speed motion, and then the beam can point to different scene at the same position. Hence, the large scene imaging can be realized. However, the range migration and azimuth resolution is azimuth variant, which makes the imaging difficult. In this paper, imaging mode of near space slow speed SAR is presented, and the variable aperture BP imaging algorithm is proposed. Simulations are given to verify the effectiveness of the imaging scheme.
