| 摘 要： | 与常规逆合成孔径雷达(Inverse syntheticaperture radar,ISAR)相同,压缩ISAR也需要进行基于回波信号的运动补偿,其中包括距离对准和相位补偿。本文提出了一种适用于压缩ISAR成像处理的相位自聚焦算法。该算法采用特征向量法解决稀疏ISAR信号的相位补偿问题。试验结果证明了该算法的有效性。

| Abstract: | As same as the conventional inverse synthetic aperture radar(ISAR), the compressed ISAR also requires the echo signal based motion compensation, which consists of the range alignment and the phase autofocusing. A phase autofocusing algorithm for compressed ISAR imaging is presented. In the algorithm, phase autofocusing for the sparse ISAR echoes is accomplished using the eigenvector method. Experimental results validate the effectiveness of the algorithm. |
