Abstract :
We investigate the effects of amplitude and phase errors on 2-D MUSIC and 2-D ESPRIT algorithms in ISAR firstly with ideal point-targets model, and then with a full-wave electromagnetic simulation of ISAR real-targets model by using 2-D finite difference time domain method (FDTD). The 2-D MUSIC and 2-D ESPRIT algorithms are implemented to form the ISAR imageries of the targets with different amplitude and phase errors, and the imaging results are compared and analysed.
