Abstract

The paper deals with the processing of linear frequency modulated signal of decameter waveband based on statistical approach of separating anomalous samples in experimental observations. Techniques for the rejection of narrow-band interferences and separation of desired signal have been developed on the basis of model proposed by the authors for a mixture of distributions. The specified techniques were simulated and experimentally evaluated.
