Error Rate Detection Method of Raw Data in Remote Sensing Satellite Image

在分析遥感卫星原始数据质量检测的基础上,文章提出了一种基于空帧数据统计在轨遥感卫星图像原始数据误码率的检测方法,该方法利用空帧数据在原始数据中有较多的占比的特征,利用空帧数据的误码率代表原始数据的误码率。经多颗卫星工程应用验证,结果表明:该方法简单实用,既统计出误码率,又记录了误码出现的具体位置和错误情况,可支撑接收站设计最优数据接收方案,为提高遥感卫星图像质量提供基础。

On the basis of analysis the quality detection of remote sensing satellite raw data,a method based on the statistics of blank frame data for determining the bit error rate of the in-orbit remote sensing satellite image is proposed in this paper.This method utilizes the feature that blank frame data has a large proportion in the raw data,and uses the error rate of blank frame data to represent the error rate of the raw data.After verification of multiple satellite engineering applications,the results show that the method is simple and beneficial.It not only calculates the bit error rate,but also records the precise location and error situation,which can support the design of the optimal data reception scheme for the receiving station and serve as a base for enhancing the quality of remote sensing satellites image.
