Abstract
For joint Inverse Synthetic Aperture Radar (ISAR) imaging, the traditional methods all process the radar data matrix through vectored manipulations, which adds burden to the calculation and storage procession. In this paper, a novel algorithm of two-dimension (2D) joint ISAR imaging is addressed based on matrix completion (MC) theory. The ISAR observation signal model is established, and the echoed signal matrix is undersampled. After demonstration of the low-rank property of data matrix, 2D joint ISAR imaging is mathematically converted into the kernel norm optimization. The joint ISAR imaging can be achieved with the inexact augmented Lagrange multiplier (IALM) algorithm. Simulated data experiments verify the effectiveness of the proposed algorithm.
