Problem statement. Methods that using phase measurements can be useful for calibration DAA. They have a potential advantage in speed over phaseless methods of calibration, because such methods achieve the minimum number of measurements per channel. At the same time, it is not always possible to technically ensure phase constancy during measurements. This causes signal phase drift, which is observed in the total DAA signal with a constant configuration.

Purpose. Consider how phase drift affects the result of DAA calibration by some methods that provide calibration for a small number of measurements per channel.

Results. The article presents that the phase drift significantly affects the results of DAA calibration by methods that using phase measurements. The maximum error becomes unacceptably large in some cases even at low phase drift rates.

Practical relevance. The results are useful for developing and already developed methods for DAA calibration in real conditions.
