摘要:
Models for underwater acoustic properties depend heavily on the windspeed and other relevant geophysical parameters. At sea such parameters will in the future increasingly be provided by satellite radars. The NARSHA (NATO Remote Sensing SHAllow water) experiment was designed to investigate the relationship between observations from satellite, airborne, and surface radars on the one hand, and acoustic observations of propagation loss, reverberation, and ambient noise on the other. Radar returns from the sea result from mechanisms comparable to those which generate sea stale noise and absorb and scatter underwater sound. The experiment demonstrated the existence of a relation between these quantities. Further investigation is necessary to indicate how reliably the effects of the interfering boundary layer on the wind can be circumvented by interrelating radar and acoustic quantities directly and to validate these relations statistically.
