| Abstract: | Describes a target method using passive acoustic sensors with discrete or impulsive acoustic signals resulting form artillery or other explosions. Presents a few methods for estimating time delay and the way to decrease the variance of bearing.An apparatus to be able estimate the time delay and target location is shown, which is composed of IC.The apparatus possesses high accuracy of estimation and convenience in use. Finally, some experimental results are given. |
