摘　　要：当探测器置于旋转平台下方时,由于平台的旋转,在探测器像面上接收到的像将按一定规律作旋转运动.根据系统基本结构,分析了成像系统的光学传输成像模型,提出了数字消像旋的简易方法,对图像处理系统的实际输出结果进行处理,而不需要采用光学消像旋和电子图像消像旋等方法,提高了系统探测处理的实时性,降低了系统设计的难度,具有较强的实用性.The image received on the image surface of detector will rotate regularly with the platform rotation. Based on the System＇ s basic frame, the optical transfer model was analyzed and one handy method was suggested to offset the image rotation. This method makes use of the actual result of the image processor and needn＇t use optical way or electronic way to offset image rotation. This mathematic method is very easy, increases the system processing speed and reduces the system＇s complexity. It is practicability.
