Abstract :
Envelope drift and jump error caused by using the envelope amplitude correlation method pulse by pulse may be as large as the length of several range bins. These errors decrease the quality of the image heavily. By using the super-resolution technique, the accuracy of the range alignment is increased, and the envelope drift error and jump error in the range alignment are decreased. Imaging results of real ISAR data show that the quality of the image is improved clearly by the super-resolution technique
