摘要
在独立射击方式下,假设目标作匀速直线运动,根据火炮角度传感器测量的高低角和方位角,用视在航路法求取射击诸元。因测量值含有跟踪误差,所求参数含有较大噪声,必须对其进行滤波。根据射击诸元求解方程找出目标参数潜在的特征,提出了一种先限幅后采用加权平均滤波的方法,对跟踪误差进行滤波。仿真表明,这种方法能有效提高目标参数的估计精度。
In independent firing mode, assumption of the uniform linear motion of target is taken, according to elevation and azimuth measured from the gun angular sensor, firing data is computed rising apparent flight path method. Because the measured value contains tracking error, parameter to compute has noise and it is necessary to filter it. This paper proposes a method, which limits amplitude first and then filters with the weighted average to filter the tracking error. Simulation result shows that the method improves the estimating accuracy of the parameter
