Structure of maximal-likelihood gauge for detection a signal with unknown amplitude and times of appearing and disappearing is considered. Substantial nonlinearity of algorithm and complication of its realization due to the double-channeled structure are discussed. Double-channeled structure simplifying the realization of the gauge of the quasi-optimal gauge is proposed. Asymptotic characteristics of proposed algorithm are found.
