Abstract:	本文提出過門檻時間數列(Cross Over Time Sequence, COTS)重建弦波振幅公式，及窄頻超音波收發換能器系統鑑別演算法。本實驗測量出一組窄頻超音波收發換能器系統的於帶通頻段內各頻的COTS，再以過門檻時間數列重建弦波振幅公式求出頻率響應，並以窄頻超音波收發換能器系統鑑別演算法計算出系統轉移函數。未來鑑別出的系統轉移函數將可以使用於超音波測距系統的改進。 This study raised the Cross Over Time Sequence(COTS) sinusoidal amplitude reconstruction formula, and narrowband ultrasonic transducer transceiver system identification algorithms. In this study, a set of COTS of narrowband transceiver transducer ultrasound system in each frequency in pass band has measured. Then reconstruct amplitude by COTS sinusoidal amplitude reconstruction formula, and calculate the system transfer function by narrowband ultrasonic transducer transceiver system identification algorithms. The system transfer function identified can be used in ultrasonic COTS ranging system improvements.
