FTB电台的原理和应用

Introduction for the working theory and application of FTB radio

随着地震勘探技术的快速发展和勘探精度要求的不断提高,震源系统和地震仪器之间的时间同步精度也随之提高。对于气枪作业而言,枪控系统产生的FTB信号,是地震仪器用来检测单炮同步性的重要指标。针对这些需求,东方地球物理公司研发的FTB电台具有信号传输精度高、工作状态稳定、信号传输延迟小的特点,实现了FTB信号的实时传输,满足了施工精度的要求。

With the rapid development of seismic exploration technology, more and more highaccuracy technologies are required, especially the time synchronization between the seismic source system and the instrument is particularly important. The FTB signal generated by the air gun system is an important indicator of synchronization. According to these demands, the surveying service center of BGP has developed FTB radio, which realizes the real-time transmission of the FTB signal.
