A Research on Phase Measuring Algorithm Based on Multiple Sampling

阐述了一种相位差测量算法。首先介绍了Multiple Sampling算法的理论根据,并且进行了算法仿真实验和误差分析,然后在此基础上进行了谐波及噪声分析,提出了针对可变频信号的算法仿真方案,结果表明在增大白噪声幅度的情况下,初相最坏误差仍控制在高精度工程标准内。

This paper presents a phase measuring system based on multiple sampling.It first introduces the Multiple Sampling ra- tionale,and its simulation experiments and error analysis.Then it puts fdrward the adaptive measuring method,followed by the measuring plan of phase.The tests show that this system has high accuracy and environmental adaptability.
