摘要
轻便高频可控震源是一种用于工程探测和浅层地震勘探的激震设备 ,它的主要作用是提供参数得到严格控制的Chirp信号 (LFM )。围绕信号的产生和参数的控制 。
Portable High-frequency Vibrator (PHV) is a kind of vibration source for engineering detection and shallow seismic survey. Main function of PHV is to generate a Linear Frequency Modulated (LFM) signal with strictly controlled parameters. Centered on the generation and control of LFM signal, both hardware and software design and implementation of the measurement & control system was presented in this paper.
