Abstract

Abstract

Different sensor placements have a great influence on the accuracy in Phase Differences Of Arrival (PDOA)-based hit position estimation. Compared with single time target localization, estimation of hit position is more complex because of additionally considering speed and its direction. In order to choose an adequate sensor geometry for source localization, a method of evaluating the performance of sensor placement by sensitivity analysis is proposed, which provides a theoretical foundation for analyzing the accuracy of hit position estimation. Then the sensitivities of three typical sensor geometries are analyzed and Cramer-Rao Lower Bound is compared to verify the effectiveness of the proposed method using computer simulations.
- Hit position estimation,
