COMMUNICATION AND TARGET DETECTION THROUGH ICE BY MEANS OF SEISMIC ACOUSTIC SIGNALS

Abstract

Seismic-acoustic signal transmission experiments, employing novel seismic transducers on land and lake ice as transmitters and conventional hydrophones in water beneath the ice as receivers, are described. The observed influences of wave excitation and propagation phenomena on the signal character of transmissions through earth, ice, and water are discussed. Applications of seismic-acoustic systems for communications and target detection are indicated. (Author)
