对阿达玛变换光谱测量中所缺数据的分析处理
Analysis and treatment of Hadamard transform measurement for the case of being data short
摘要
对于阿达玛(Hadamard)变换光谱测量中缺少测量数据的情况,推导出估算值的误差公式.并得出结论:当缺少测量数据时,可随机地在已得的最大测量值和最小测量值之间取值以补足数据点,再由计算机解码,仍能以相当的精度获得所测光谱信息.
Abstract
The error of evaluation of Hadamard transform measurement for the case of being data short is analysed and a formula is deduced. It comes the conclusion that when data are not complete one can make up the absent data by rand on values within the interval between the maximum and minimum readings of the data in hand, and decoding by computer, one can get the information of the spectrum in appropriate accuracy.
