Statement of the problem. A large number of applied problems in radio physics is associated with the need to assess the efficiency of receiving signals with unknown times of appearance and disappearance. At present, algorithms for the functioning of narrow-band means of detecting signals with unknown parameters are well studied. With the advent of RES with ultra-wideband signals (UWBS), it became necessary to develop new algorithms for processing such signals.

Purpose. Improving the efficiency of UWBS detection in the presence of interference and a priori uncertainty.

Results. An algorithm for detecting ultra-wideband signals of unknown shape with unknown moments of appearance and disappearance in the presence of Gaussian white noise and Gaussian narrow-band interference has been developed.

Practical significance. The developed algorithm makes it possible to evaluate quantitative indicators of the efficiency of the equipment for detecting ultra-wideband signals in various conditions of a signal-interference environment and in the presence of a priori un-certainty.
