    Abstract: 本篇論文將射箭選手瞄準的軌跡建立數學模型,其中瞄準軌跡是利用高速攝影機以每秒1200張取樣頻率。模擬方法是使用自動回歸移動平均具外部輸入(ARMAX)的數學模型來模擬射箭選手的瞄準軌跡,估測數學模型的係數是採用最小平方誤差及基因法則。最小平方誤差所估測的參數為區域最佳解,而基因法則所估測的參數較接近全域最佳解,是兩者間最主要的差異。利用第一部分瞄射軌跡所訓練數學模型的參數,去估測第二部份鬆弦放箭運動,本論文發現,對於高級的選手他們的第一部份瞄射軌跡與第二部份鬆弦放箭運動,可以用相同的三階ARMAX數學模型
    In this paper, the linear time invariant auto-regressive exogenous moving average (ARMAX) process is adopted to model the aiming trajectory the aiming procedure recorded by a high speed camera at 1200 frames/sec. The minimum mean square error (MMSE) crite
