Abstract:

Experimental and theoretical data are presented on the performance of seismic wave transmitters consisting of arrays of 80-Hz 10-watt-max resonant seismic transducers. The influence of the structural dimensions of seismic media on the transmission of continuous seismic wave CSW signals is analyzed by a comparison of seismic radiation patterns obtained in the field with phase-controlled transducer arrays. Practical applications of phase-controlled seismic transmitter arrays are discussed, and equipments, circuits, and measurement methods are described. Author
