星载成像光谱仪地物信息的统计控制

STATISTICAL CONTROL OF GROUND SCENE INFORMATION OF SPACEBORNE IMAGING SPECTROMETER

分析了星载成像光谱仪地物信息特征,提出并实现了一种地物信息统计控制方法。该方法使系统具有较理想的准确信号量化率与信号数据率;经计算机数字仿真及电路信号模拟表明:系统具备快速的控制过渡过程。

In this paper, a method of statistical control of the ground scene information is presented and realized by means of analyses of the features of ground scene information received by the Spaceborne Imaging Spectrometer. This method makes both the accurate signal quantization rate and the signal data rate of the system be relatively perfect, and the results of computer digital simulation and circuit signal imitation indicate that the system possesses a fast control transition process.
