The tracking algorithm of passive acoustic detect system

The passive acoustic localization technique is frequently used to detect and track the target that emitting acoustic signals. It is widely used by the military for its advantages of concealment and anti-jamming. This paper presents a new fusion algorithm for the passive asynchronous multi-acoustic-sensor system which only supplies the time delay bearing information. First adjust the time-space of supplied bearing information which supplied by asynchronous multi-acoustic-sensor, then use pseudo-linear kalman filter (PLE-KF) to track the aim. Monte Carlo simulation shows this algorithm attains the localization precision of our project.
