摘要 提出了一种基于压缩感知(CS,compressive sensing)的SAR对多舰船目标的成像算法。通过将多舰船目标成像转换为在某种基下具有稀疏表示的信号重建问题,从而满足CS理论对信号恢复重构的要求,获得比传统成像方法更高的方位分辨率。实测数据的处理验证了该算法的有效性。 A new approach based on Compressive sensing(CS) is presented for SAR imaging of multiple ships.The multiple ships imaging is converted into a problem of sparse signal reconstruction with an orthogonal basis,and then the sparse reconstruction of CS is realized and a theoretical upper bound of the cross-range resolution is obtained.Real measurement data demonstrate the effectiveness of the CS imaging algorithm.
