Abstract
The selection of interval of ISAR ship target includes selection of time position and selection of length of the time window. A definition of image contrast is given and a fast algorithm to select the time position and the length of the time window which bases on image contrast is proposed in this paper. According to the features of ISAR ship imaging, a simplified algorithm to determine optimal time position of top view or side view ship images is presented. Integrated echoes from that time, the optimal coherent time will be obtained by making the image contrast maximum. The effectiveness and practicability of the method are proven by real data processing.
