A tunable GaAlAs diode laser is used as a chirp signal source, the distance is detected by calculating the beat frequency.
由可调谐半导体激光器产生一个啁啾信号，通过测量拍信号频率计算距离。
In this paper we separately use White noise and chirp signal as signal source, and apply simulate software MATLAB to research the time delay between the transmitted signal and the received signal.
本文分别以白噪声及扫频信号为信号源，采用计算机仿真软件MATLAB，对声波在声发射端和接收端之间的飞渡时间的互相关估计进行了计算机仿真研究。
