通常在目标均匀旋转或近似均匀旋转的条件下,采用传统的距离-多普勒(Range Doppler,RD)成像方法就能够获取目标ISAR图像,但是实际应用中,目标运动状态复杂,采用传统RD成像方法获取的ISAR图像会出现散焦和拖尾,不能准确反应目标形貌信息,因此,复杂运动目标ISAR成像仍然是研究的热点和难点。
(2) an explanation is found for the observation that the scatterer Doppler frequency is slightly less than the Doppler frequency corresponding to the fundamental wave phase speed; (3) a representative non-Bragg cross section of a breaking wave can be obtained; and (4) a breaking wave surface ...
