True Time

The emergency of wireless sensor network provides a distributed, low cost and flexible solution for acoustic localization system. Location precision is a critical parameter for this system. In this paper, we use True Time, which is a Matlab/Simulink co-simulation block library to establish a simulation environment and establish a relationship between localization precision and PRR (Package Reception Rate). With the PRR decreasing, the AOA precision is get lager. Hence, in a given spatially deployed sensor network location system, the location precision will get larger. Therefore, the PRR should be controlled in a rational level, which is depended on the trade-off between performance and efficiency.

Passive Acoustic

The simulation system for passive acoustic sensor network is an important part of information fusion system. Its main function is to simulate the detection process of acoustic sensor network and produce the simulation data which is needed for testing and evaluating the target tracking algorithms. For implementation of simulation system, the target motion model and the measurement model of passive acoustic sensor must be built, and a scenario will be defined in advance when it is running. This paper discussed the passive acoustic sensor network model and gave an information fusion system structure for passive acoustic sensor network. Then the basic principle of target detection for acoustic sensor is stated. Finally, we illustrated the operation process of a simulation system for passive acoustic sensor network.
