Efficiency of the Detection of a Specific Wideband Signal under a Priori Parametric Uncertainty

A quasi-plausible algorithm is synthesized for detection of ultrawideband quasi-radio-signal with arbitrary shape and unknown amplitude, initial phase and duration. Statistical characteristics of the efficiency of the proposed algorithm (false-alarm and signal-omission probabilities) are determined. A decrease in the detection efficiency due to a priori ignorance of the signal parameters is characterized.
