On statistical adaptation of the order filters for the signal form and its noise specificity

This paper is aimed to the improvement of the quality of the data of vibro-seismic research under the condition of the wave form preservation of a sounding signal. For this purpose, it is offered to use the order statistics filters. As seismic data are mostly harmonic or frequencymodulated (or sweep) signals in the frequency range 1 to 10 Hz, these filters must be adapted so as to suppress noise but not unduly distort a signal because such filters possess specific features. To this end, it is reasonable to attract statistical adaptation of such filters for the form of a signal and specificity of noise To illustrate the proposed methodology of order statistics filters adaptation, models of a sweep signal from the frequency band of 72-82 Hz were processed and the quality of the signal enhanced considerably over the quality of the signal without processing.
