Abstract—The algorithm for detecting the coherent-pulse signals against correlated interferences is considered. It is invariant to both the carrier frequency of the signal and the statistical characteristics of its fluctuations. Its optimization is implemented in terms of the signal-to-interference ratio. The structure of the optimized procedure for extracting the signals with the limited statistics is found under the arbitrary signal-to- interference ratio. The efficiency of the introduced procedure is estimated. A technique is presented for calculating the detection characteristics. The usefulness of the obtained results for designing the corresponding detection devices is confirmed by a number of examples of numerical calculations.
