【摘要】 提出了一种新的基于合作目标的动基座传感器误差绝对配准方法。该方法利用所获得的合作目标位置信息,将载体平台姿态角偏差转换为传感器测量偏差中的一部分,并建立偏差状态方程和测量方程。在此基础上,采用广义最小二乘方法以实现传感器测距误差的估计,不敏滤波的方法则用于实现平台载体的姿态偏差和角度测量偏差的实时估计。仿真结果表明,该方法实现简单,收敛速度快,可以实现单部动基座传感器的偏差估计。更多还原

【Abstract】 A novel bias estimation method for solving maneuvering sensor bias correction problems based on cooperation target is proposed. Using the estimation position of cooperation targets,the gesture angle biases of a moving base can be converted to the measurement biases,and an error system model for computing all kinds of biases is proposed. Based on the decoupling model,a generalized least squares method is used to estimate the range measure bias,and the unscented Kalman filter is used to estimate the other biases. The simulation results show the approach can be easily carried out and has the rapid convergence rate,which can estimate the biases of single maneuvering sensor.更多还原
