多传感器环境下目标跟踪的方位配准方法

A Method of Azimuth Registration Error in Target Tracking With Multisensor Environment

通过建立传感器无误差和有误差情形下的坐标之间的转换关系,用方位偏差扩展目标状态向量。利用扩展卡尔曼滤波器估计这种偏差,并用估计偏差对传感器测量进行校正。仿真实验结果表明这种方法是有效的。

This article proposes a scheme that the azimuth error can be used to extend the target vector, by setting up the conversion relation between the coordinate system without sensor error and the one with sensor error. The mentioned error can be estimated by using the extended Kalman filters, and the estimated error is used for calibrating the sensor measurement. Simulation results show that the scheme is feasible.
