一种海面舰船目标ISAR成像时间段选择方法
New ISAR imaging interval selection method for ship targets on the sea
摘要
Abstract
Ship targets on the sea swing because of the sea wave, which leads to instability of the rotation speed and variation of the image project plane.As a result, imaging interval selection should be taken into consideration in order to obtain a high quality ISAR image.In this paper, firstly, the relationship between effective rotating speed and image project plane is analyzed in detail, by which the conclusion that the image project plane is stable and the resolution of the ISAR image is best when the valid speed of rotation of a ship target is highest is drawn.Then a new method to select favorable imaging interval based on the rotation speed of ship targets is proposed.In comparison with existing methods, the proposed one can select a better period for ISAR imaging, which leads to an imaging result with higher quality.The effectiveness of the proposed method is verified by simulation and real data processing result.关键词
