Abstract

The paper deals with a positioning acoustic method that uses the time difference of arrival estimation through the cross-correlation techniques. The method will be applied for the determination of the position of the impact points of the air-dropped bombs. Firstly, the acoustic methods for position detection are presented, and the methodology for air dropped bombs impact points position estimation is chosen. The proposed method and the positioning system architecture are described.
