基于自适应Chirplet分解的舰船目标ISAR成像
The ISAR Imaging of Ship Based on Adaptive Chirplet Decomposition
-
摘要: 相对于飞机目标的ISAR成像，舰船目标的ISAR成像同样具有重要意义, 但国内对舰船目标的成像研究刚刚开始。由于舰船运动的复杂性，使得舰船目标的成像条件要比飞机目标复杂得多，传统的针对飞机目标的成像方法已经不能满足要求。因此，该文提出了基于自适应Chirplet分解的舰船目标成像方法，得到了舰船不同时刻的瞬态ISAR像。

Abstract: The ISAR imaging of ship is significant relative to plane. The imaging condition of ship is more complicated than plane due to the complexity of the ships movement, and the conventional ISAR imaging algorithm to the plane can not be satisfactory to the ship. So, a new method based on adaptive Chirplet decomposition is proposed here, the instantaneous ISAR ship image is obtained. -
