EXPERIMENTAL ASSESSMENT OF NOISE STABILITY OF THE COMBINED RECEIVER IN INFRASONIC FREQUENCY RANGE
Comparative assessment of noise stability of the combine receiver at different algorithms of processing of the scalar, vector and tensor parameters characterizing the sound field created by a noise object in infrasonic frequency range is executed. It is shown that real operating conditions of a receiving system in infrasonic frequency range essentially differ from model conditions of a free space. As a result, additive algorithms of signal processing which traditionally are considered as optimum lose the efficiency, and the efficiency of multiplicative algorithms of processing can be increased by increase in volume of the processed information. The results of processing of experimental data confirming significant increase in potential noise stability of the combine receiver at increase in number of the informative parameters characterizing a sound field of the rustling object in scalar - vector and tensor description are given.
