The new quasi-likelihood algorithm is considered for detecting a radio signal with the unknown amplitude, duration, initial phase and inexactly known envelope shape against Gaussian white noise. The structure and the statistical characteristics of the introduced detection algorithm are found. The influence is studied of the difference in the envelope shapes of the received and reference signals upon detection efficiency.
