We consider separate space-time adaptive signal processing against the background of combined interferences, which involves the fixation of weight vector of spatial signal processing against the background of noise interferences for the time of adaptive interperiod signal processing against the background of clutter. By means of mathematical modeling and hydroacoustic simulation the fixation interval is estimated, which keeps in allowable limits the losses in quality of noise interferences suppression.
