摘要
讨论了用被动式传声器阵列估计目标方位角的问题.分析了时延估计的几种方法,提出了减小方位角估计误差的途径,给出了几种因素对误差量的影响;并设计了一种能用于时延(方位角)估计的装置;最后,给出了几组试验结果,证明了文章所提出的时延估计方法的准确性、可行性和装置的可靠性.
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.
