    • A method and apparatus is provided for acoustic ranging by application of linear period modulated sound. In one aspect of the instant invention, an apparatus is provided for acoustic ranging by application of linear period modulated sound. The apparatus includes at least one source adapted to generate at least one modulated Doppler invariant signal and at least one receiver deployed along a seismic sensing cable, wherein the receiver is adapted to receive at least one modulated Doppler invariant signal from the at least one source. The apparatus further includes a signal processing unit adapted to determine the propagation time delay between the source and the receiver using the modulated Doppler invariant signal and the received Doppler invariant signal.
    • 提供了一种通过应用线性周期调制声音进行声学测距的方法和装置。 在本发明的一个方面,提供一种通过应用线性周期调制声音进行声学测距的装置。 所述装置包括适于产生至少一个调制的多普勒不变信号的至少一个源和沿着地震传感电缆部署的至少一个接收器,其中所述接收器适于从所述至少一个源接收至少一个调制的多普勒不变信号。 该装置还包括信号处理单元,该信号处理单元适于使用调制的多普勒不变信号和接收的多普勒不变信号确定源和接收机之间的传播时间延迟。
