| 摘 要： | 为提高被动声定位系统的定位精度，本文提出了一种基于圆阵测量的扩展卡尔曼滤波算法，该算法首先对时延测量值进行预处理，以预处理直接作为卡尔曼滤波器测量方程的输入量，并利用台劳级数对非线性测量方程进行线性化。数值计算和仿真结果表明，该算法是较好的滤波、跟踪效果。

| Abstract: | With an aim to enhance the precision of passive location of an acoustic target, an extended Kalman filtering algorithm on circular array is developed Measurement of time delays is first processed, non linear observation equation of the Kalman filter is then linearized using the Taylor series The pre processed time delays are used as the observation values in the equation of observation Results of computer simulation showed that it has good filtering and tracking performances |
