description: The subject of the graduate qualification work is research of multichannel signal detection algorithms under conditions of a priori uncertainty. The purpose of the work is to study various detection algorithms and to modify the optimal one for the possibility of practical application. As a result of the study, the following algorithm was developed: the optimal algorithm for joint evaluation-detection of a signal of unknown duration, a signal of unknown duration and unknown amplitude, a signal of unknown duration in noise of unknown intensity. For the latter case, an unbiased algorithm and a signârank algorithm are considered. It was found that all algorithms lose to the algorithm for a fully known signal, but for the first case the loss is about 0.2 dB, for the second 0.25 dB, the same figure is characteristic of the unbiased algorithm, and the signârank algorithm loses in the signalâtoânoise ratio 0.6 dB. A modification of the algorithm from the first case is also proposed to stabilize the level of false alarms and thereby increase its practical significance.
