“…Since ISAR imaging of space target is able to provide motion parameters and structure features of the target [9], it is of great significance to develop a theoretical scattering model on ISAR imaging. A research on the theoretical and practical foundations of two-dimensional (2D) ISAR image collection and processing is made by Gombert and Beckner [10]. Yao and Zhou [11] simulated the ISAR imaging based on the scattering field calculated by the PO and ILDC (incremental length diffraction coefficient) methods.…”

An efficient algorithm is proposed for the radar cross-section (RCS) prediction of complex target with electronically large size, which is a combination of geometrical optics and physical optics (GO–PO) method. The method taking the multiple reflections into account is applied to the electromagnetic scattering analysis of a satellite model. Then RCS curves of entire satellite model and the model without antenna structure are figured out. Based on the simulated echoes, the traditional inverse synthetic aperture radar (ISAR) images are discussed. Moreover, an application of motion compensation technique based on the joint time-frequency analysis is presented for ISAR imaging of the moving satellite that has both translational and rotational movements. Numerical results show good performance of GO–PO method in accuracy and efficiency and the great influence of the antenna with corner structures on the scattering characteristic of the satellite.
