PERSONAL COMPUTER AIDED ENGINEERING (PC CAE) OF UNDERWATER TRANSDUCERS AND ARRAYS

NEW PC CAE CAN PROVIDE SIGNIFICANTLY IMPROVED R&D OF UNDERWATER ACOUSTIC TRANSDUCERS AND ARRAYS BY EXPLOITING CREATIVE NEW MATHEMATICAL MODELS AND OUTSTANDING, LOW-COST COMPUTER SYSTEMS. INNOVATIVE SOFTWARE WILL LEAD TO NEEDED IMPROVEMENTS IN PIEZOELECTRIC TRANSDUCER DESIGN AND MATERIAL-PARAMETER EVALUATIONS. MAST WILL INCLUDE ARRAY PERFORMANCE PROGRAMS OF IMPORTANT FORMS WITH SOLUTIONS OF ELEMENT VELOCITIES, FOLLOWED BY BEAMFORMER AND SIGNAL-PROCESSING FUNCTIONS. IMPROVED MEASUREMENT TECHNIQUES WILL PROVIDE SUPERIOR CHARACTERIZATION OF MATERIALS, INCLUDING TROUBLESOME COMPLAINT MATERIALS. DEVELOPMENT OF PREPROGRAMMED, USER-FRIENDLY PC CAE UNITS WILL INCREASE INDIVIDUAL PRODUCTIVITY AND FACILITATE PERSONNEL TRAINING. INEXPENSIVE HIGH-CAPACITY DATA STORAGE UNITS MODIFY THE STRATEGY FROM VERSATILE GENERAL-PURPOSE CAE TO MANY SPECIAL-PURPOSE USER-FRIENDLY CAE SUBSYSTEMS. MANY OF THESE DEVELOPMENTS CAN BE ADAPTED TO OTHER USES SUCH AS ANALYSES OF ANTENNA ARRAYS, ACCOMPLISHED BY COMBINING PORTIONS OF PC CAE AS BASIC SOFTWARE COMPONENTS FOR ANY SYSTEM. PC CAE WILL HAVE UNLIMITED EXPANSION POSSIBILITIES BY USING CAREFULLYDEFINED SUBROUTINES AS IN EISPACK, LINPACK, AND OTHER SOFTWARE LIBRARIES. NEW MODULES MAY BE ADDED AS IN AI SYSTEMS BY HAVING EXPERTS DESCRIBE THEIR DESIGN METHODS. THE SOFTWARE WILL PERMIT EXPERTS TO DEVELOP NEW SYSTEMS RAPIDLY, AND LESS-SKILLED PERSONS CAN PERFORM SUPERIOR DESIGNS.
