GMS展宽云图实时接收和图象处理系统

A system for GMS stretched data realtime receiving and image processing

GMS展宽云图实时接收和图象处理系统由卫星信号接收设备、实时高速数据接口,图象处理三部分组成。系统的主要工作原理:天线接收的卫星信号,通过接收机,解调器和同步器,将GMS展宽数据流送到高速接口板;经数据缓冲后,计算机一边将展宽数据存入硬磁盘,一边对所选的1024×1024 ×8bit窗口中的图象实时地在高分辨屏幕上进行伪彩色显示。

This system consists of a receiver,a real-time high speed interface and an image computer-processing subsystem. The main principle is that the GMS frame date are transmitted to the high-speed interface through, the demodulator and synchronizer. Then the buffered data are put into three files (i. e. document file, infrared and vissible files) and ingested in a hard disc with large capacity, at same time a selectable-1024 1024-pixel image is shown on the high resolution screen in the real-time and pseudocolor mode.
