Non-Stationary Random Wiener Signal Detection with Multistatic Acoustic System

Abstract

The paper presents detection rule for multistatic reception of the non-stationary acoustic signal. The detection rule is obtained using maximum likelihood approach. Usually angular beam forming is applied to microphone array to localize spatially distributed emitters. In the paper, the time difference of arrival estimates of incoming acoustic emissions are used to localize their sources. The paper proposes wide frequency band acoustic noise source detection and localization enhancement using multistatic reception system. The paper shows experimental result on localization of source of wide frequency band emission by sound pressure imaging. All passband bandwidth of incoming signal is processed simultaneously. The localization is provided in range-cross range-elevation coordinates. The proposed technique may be suitable for 4D imaging in non-destructive testing and in ultra-wideband acoustic emitters’ detection and localization. One of particular applications concerns testing of aircrafts landing regime and health monitoring of their engines at landing/take off.
