In this paper, a gain control loop which operates in synthetic radio telescope is described. The influence of noise on the variation of the gain is discussed in some details ; the gain-lock loop is described; the relation between noise power and variation of gain is derived; the formula for determining the threshold of unlocking is given and the experimental results are displayed in Fig. 6 and Fig. 7. In this paper, the steps taken to decrease the influence of noise are also discussed.
