Expressions for detection characteristics of symmetrical general form signal are founded when arrival time, duration and amplitude of the signal are unknown and there are side effects on the boundary of a priori area. The influence of boundary effects of a priori area on the precision of characteristics are investigated by means of statistical computer modeling of bell-like signal detection algorithm.
