Abstract

The co-prime-sampling SAR can effectively alleviate the contradictory relationship between spatial resolution and swath width by applying co-prime sampling in azimuth. In order to achieve accurate imaging of co-prime-sampling SAR on the condition of non-negligible range cell migration, an imaging method based on 2D sparse signal reconstruction is proposed. The 2D observed signal is intercepted and the corresponding sparse dictionary is constructed both according to the Doppler parameters of each range gate. An improved 2D signal sparse reconstruction algorithm is used to perform sparse scene reconstruction. Simulation results are provided to demonstrate the effectiveness of the proposed method for sparse scene imaging.
