Abstract: Using acoustic sensor, object’s azimuth and attribution can be gained by analyzing the noise of infrasonic wave which the sensor receives from the object. By founding the network of acoustic sensors, and fusing the multi-sensors’ information in the network, can ascertain the object’s location. So the orientation algorithm and its implementation is one of kernel technique of the acoustic sensor network. This paper discusses the classification of orientation algorithm based on the characteristic of acoustic sensor network at first, and then describes an effective algorithmic choosing mechanism, which can decrease the effect of time-delay to the object’s orientation. At the same time, this paper imports a solution of parallel process and data storage, in order to reduce the complexity of object’s orientation algorithm and improve the processing efficiency. Conclusive remarks are addressed at the end, as well as demonstrating the method’s validity by emulating.
