Target detection and tracking based on information geometry for sensor networks

Abstract

In this paper, the application of information geometry is explored in an attempt to gain a better understanding of sensor system issues for target resolution and tracking in ground-to-air sensor networks. In particular, the Fisher information distance between two targets is used to measure the target resolvability in the region covered by the sensor system and is approximately calculated when it is close enough. And then, the accumulative information is proposed to analyse the resolution of the target on the same detection cell with respect to one measurement model. Furthermore, the single step tracking method is presented based on Fisher information with single bearings-only sensor. The analysis results show that the information geometry is able to offer an effective solution method aiming at some sensor network problems.
