Noise Tolerance of Improved Max-min Scanning Method for Phase Determination

摘要

This paper presents and demonstrates the enhancement of noise tolerance exhibited by the improved Max-Min scanning method (IMMS) for phase determination. Numerical simulations and various tests indicate that the IMMS has a good tolerance to certain ranges of noise. One of the IMMS applications, an online method to calibrate the phase shifter, is presented as well. This improved algorithm provides an easy and convenient way to inspect the linearity and the non-uniformity of the phase shifter. It is suitable for use in assessing the reliability of the phase shifting setup in real time.
