摘要：

The paper is devoted to the Allan variance usage for output signal fluctuation analysis of weak signal receivers. The tri-band microwave receiving system for the new radio telescope RT-13 of Institute of Applied Astronomy of Russian Academy of Sciences is considered. The Allan variance correction for signals with << deadtime >> in data acquisition is developed. Output stability of the receiver is investigated in terms of noise fluctuation type - white, flicker, drift, etc., and their time stability intervals calculation. Investigations are performed in S-, X-, and Ka- receiver bands. The influence of the input cryogenic stage temperature on output receiver signal is considered also.
