本文提出新創相位資訊進行系統鑑別演算法。本實驗測量出一組窄 頻超音波收發換能器系統的過門檻時間數列(Cross Over Time Sequence, COTS)，過門檻時間數列加上系統相位的假設求出頻率響 應，並以新創相位資訊進行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可以使用於超音波測距系統的改進上。 This paper presents a new creative phase information for system identification algorithms. In this study, a set of measured narrowband transceiver transducer ultrasound system over the threshold time series (Cross Over Time Sequence, COTS), over the threshold time series calculated with the assumption that the system phase-frequency response and phase information to new record for system identification algorithms to calculate the system transfer function. In the future, identify system transfer function can be used in ultrasonic ranging system to improve on.
