Abstract :
In this work a three-dimensional ISAR imaging for spin target by back projection algorithm is presented. The space-time feature of ISAR signal is described. The principle of back projection algorithm is analysed, and a three-dimensional ISAR image reconstruction procedure using the back projection (BP) algorithm is developed. Otherwise, we introduce the point-spread function (PSF) to analyze the space resolving power of the back projection algorithm. The calculated results of the 3-D point spread function of nonlinear motion 3D ISAR is presented.
