本論文結合窄頻超音波換能器系統鑑別演算法與飛行時間序列法，提出超音波絕對飛行時間的量測方法，突破原本峰谷時間序列法僅能夠量測相對距離的限制。本論文先以電腦模擬系統為平台，驗證本論文提出之測距演算法正確且具有高量測性能，再透過實際測距平台進行測距性能的實測。In this paper combined with system identification and Peak Time Sequence Method proposed the method of ultrasound absolute time of flight measurement, breakthrough the original Peak Time Sequence Method can only be measured relative distance limit. In this thesis, computer modeling platform used to validate the algorithm correctness and ranging performance, then the actual distance measurement platform validation of the actual ranging performance.
