振幅和差测角中信号积累与归一化处理顺序研究

Sequence of Signal Accumulation and Normalization in Angle Measuring Method by Sum-Difference Amplitude-Comparision

振幅和差法测角中角误差信号的提取一般要经过积累与归一化两个步骤,两个步骤的先后顺序将直接影响角误差信号的精度。论文研究了积累与归一化的先后顺序对角误差精度的影响,研究表明先积累后归一化的效果更好。

There are two important steps, signal accumulation and normalization, in angle measuring method by sum-difference ampli- tude-comparision. The sequence of them directly influence the accuracy of angle error signals. The influence of of sequence is studied in this paper, and the experiments resulets show that the performance is better while signal is accumulated before normalization.
