Abstract: Seismic surveying techniques are described in which seismic receivers in a seismic array are used as seismic sources. These receiver-sources may be used to determine the near-surface structures of the Earth, geometric properties of the survey array, receiver locations and operations of the survey array. The receiver-sources may be driven by drive sequences to produce amplified receiver-source signals, plane waves, surface waves converging towards a point inside the seismic array, surface waves sweeping through the seismic array and/or the like. The receiver-sources may comprise geophones, hydrophones, accelerometers and/or the like. A driver may be used to drive the receiver-sources and the driver may be controlled by a processor. By encoding drive sequences, seismic data generated by the receiver-sources may be separated from seismic data generated by another seismic source in the seismic array. Similarly, seismic data can be separated by controlling the frequency of seismic signals produced by the receiver-sources.
Abstract translation: 描述了地震测量技术，其中将地震阵列中的地震接收机用作地震源。 这些接收器源可以用于确定地球的近地表结构，测量阵列的几何特性，接收器位置和测量阵列的操作。 接收器源可以由驱动序列驱动以产生放大的接收器源信号，平面波，朝向地震阵列内的点会聚的表面波，通过地震阵列扫掠的表面波等。 接收器源可以包括地震检波器，水听器，加速度计和/或类似物。 可以使用驱动器来驱动接收器源，并且驱动器可以由处理器来控制。 通过对驱动序列进行编码，由接收机源产生的地震数据可以与地震阵列中的另一个地震源产生的地震数据分开。 类似地，地震数据可以通过控制由接收机源产生的地震信号的频率来分离。
