遥感信号星上预处理

PRE-PROCESSING OF REMOTE SENSING SIGNAL ON SATELLITE

描述了对FY-1气象卫星扫描辐射计所探测的五通道地球信号进行星上实时数字预处理的方法。最终输出数字量高分辨率图像传输资料HRPT和经图像几何畸变校正的自动图象传输资料APT。

This paper describes a method of on-satellite real-time digital pre-processing for the five-channel earth signal detected by FY-1 Meteorological Satellite Scanning Radiometer. Finally the digital high-resolution picture transmission data (HRPT) and the automatic picture transmission data (APT), in which image geometric distortion has been correctel, are outputed.
