The article contain quasi-likelihood algorithm detection of an ultra-wideband quasi-radiosignal of a random shape with unknown am-plitude, initial phase and duration. Under the ultra-wideband quasi-radiosignal is understood the signal, the structure of which is similar to narrowband radiosignal without performed relatively narrow bandwidth condition. Proposed flowchart quasi-likelihood detector. The analysis of the synthesized algorithms is fulfilled, probability of errors is founded. It is shown, that the duration of the signal ignorance may lead to a significant reduction in the accuracy of quasi-likelihood detection. The obtained results of synthesis and analysis detection algorithm ultra-wideband quasi-radiosignal with unknown duration allow optimizing parameters generated signal to improve performance of signal detection.
