Method for express-calibration of the sensitivity of a multichannel adaptive phase demodulator.

Abstract

In this paper, we present a method for calibrating a multichannel adaptive phase demodulator. The proposed method consists of introducing a known phase modulation with variable amplitude into the channels of the demodulator, constructing a transient response and determining with it the calibration coefficient for each channel of the demodulator. The process of calibration is automated and takes 2 seconds. Express calibration method gives an opportunity to mitigate a sensitivity spread through the channels of adaptive phase demodulator.
