Multistatic Reception of Non-stationary Random Wiener Acoustic Signal

摘要

The chapter presents a detection rule for multistatic reception of the non-stationary random Wiener acoustic signal. The rule is obtained using the maximum likelihood approach. In the chapter, the localization is carried out using time difference of arrival estimates from multistatic receiving positions. It enables simultaneous processing of the frequency bandwidth, which is close to human hearing range. The approach is promising in detection and localization enhancement. The chapter shows an experimental result on the localization of a source with a fractional bandwidth of emission equal to 2. The localization is provided in range-cross range -elevation coordinates. The proposed technique is suitable in acoustic emitters' detection and localization for non-destructive testing. Particular applications concern testing of an aircraft's landing regime and health monitoring of its engines at landing/take off.
