目标的轨迹反应了目标的运行位置,如果能够提前一步得到目标的运行位置,就能提前采取必要的措施,然而目标的轨迹预测受到各种因素影响难于准确的计算.提出了一种基于多项式预测滤波的机动目标轨迹预测方法(MPF),该方法利用目标的前k步位置,分别从直线、斜线、曲线3个方面预测目标运动的下一个轨迹位置.仿真实验验证,此方法较其他轨迹预测方法具有较高的准确性.
The goal path reflected the goal operating position.If the goal operating position is obtained ahead of time,we can take the essential measure.However,the forecast of goal path is difficulty to accurately computate because of various kinds of factor influencing on it.This article proposed a flexible target path forecast method based on the multinomial predictive filter(MPF),which uses the previous k-step position,and predicts the next path position from the straight line,the oblique line and the curve separately. The simulation confirms that the algorithm proposed in this paper has higher accuracy than other path prediction method.
