Target Localization System Based on Time Difference of Arrival
Cao Xue · Command Control & Simulation · 2006
This paper, discusses target localization by using the theory of acoustic passive localization in the air. It establishes a planar wave acoustic passive localization model, and designs the general structure of the position system using simple passive acoustic sensor arrays. It proposes a simple method to design calculating circuit of time difference of arrival and the circuit is fit for target localization in time. It could eliminate the disturbance of the effective sound velocity when using the system to position distant targets. Several tests show this system is feasible, but it needs amelioration when position near targets.
