摘要
重点研究了导引头图像数据凝视发送方式和线扫交替发送方式模式下的信号转换方法,并比较了FIFO操作和乒乓操作2种信号处理的特点,以及它们对系统采集时序的影响;经实验测试,采用乒乓操作方法对线扫发送的图像信号进行处理,简化了图像采集的软件设计。
The paper emphasizes in discussing the signal transfer method with the modes of seeker data gaze transmitting mode and line scanning alternation transmitting mode.The comparing the characteristics and the influence on system acquisition timing of the following two signal transmission is in processing：the FIFO operation and ping-pong operation.Experiment tests indicate that the ping-pong operation will greatly simplify software design of the image acquisition system in image signal of line scanning transmitting mode.
