Оптимальное обнаружение сигналов на фоне микросейсмического шума

Abstract

The problem of signal detection on a microseismic background noise is of current importance, but especially in analysis of those signals which are comparable or smaller than the level of background noise from the energetic point of view. Background noise establishes a natural restriction to the signals that can be detected by seismic tools. Under condition of a high-level noise, the conceptual mathematical model of optimal estimation of the signal parameters is proposed. Efficiency of the model is illustrated by the example of a field observation experiment.
