Abstract
DEVELOPMENT OF AN IMPROVED MODEL FOR ACOUSTIC SCATTERING FROM A TURBULENT MEDIUM IS PROPOSED, WHICH WILL USE THE SELF-CONSISTENT FIELD APPROACH TO MULTIPLE SCATTERING. RESULTS WIL BE USED TO PREDICT ACOUSTIC SCATTERING SIGNATURES AS A FUNCTION OF THE ACOUSTIC AND TURBULENCE PROPERTIES OF THE SCATTERING SYSTEM. PROJECT OBJECTIVES INCLUDE A DETERMINATION OF THE COHERENT FIELD (MEAN FIELD) AS WELL AS INCOHERENT FIELDS (SCATTERED ENERGY) ASSOCIATED WITH THE SCATTERED ACOUSTIC RETURN SIGNALS FROM A TURBULENCE REGION WHICH HAS A SPECIFIED SIMPLE GEOMETRY AND PRESUMED STATISTICAL PROPERTIES. THIS APPROACH WILL PROVIDE A GENERAL AND SYSTEMATIC TREATMENT, TO ALL ORDERS IN TURBULENCE, OF THE SCATTERING OF ACOUSTIC WAVES, IN TERMS OF THE PROPERTIES OF THE TURBULENT STRUCTURE OF THE SCATTERING SYSTEM.
