Abstract
IN THIS PROJECT, AN ADVANCED UNDERWATER ACOUSTIC INTENSITY MEASUREMENT SYSTEM WILL BE DESIGNED, BUILT AND TESTED. THIS SYSTEM CONSISTS OF A MULTI-SENSOR PROBE-TYPE ARRAY, A REAL-TIME SPECTRUM ANALYZER AND A MINI-COMPUTER SYSTEM WITH BUILT-IN IN-SITU CALIBRATION CAPABILITY. THE SYSTEM IS CAPABLE OF MEASURING, DISPLAYING, AND MEMORIZING: (A) THREE ORTHOGONAL ACOUSTIC INTENSITY VECTORS AND THE TOTAL ACOUSTIC INTENSITY VECTOR, (B) THREE ORTHOGONAL ACOUSTIC VELOCITY VECTORS AND THE TOTAL VELOCITY VECTOR, (C) ACOUSTIC PRESSURE, (D) ACOUSTIC IMPEDANCE, AND (E) ACOUSTIC INTENSITY CONTOUR MAP. THE MEASUREMENT GRID POINTS CAN BE INPUTTED TO THE SYSTEM FOR POST DATA PROCESSING PURPOSES. THE STORED DATA OF PRESSURE, VELOCITY, IMPEDANCE AND INTENSITY TAKEN AT A GREAT NUMBER OF GRID POINTS AROUND AN OBJECT CAN BE STORED IN MEMORY TO BE RETRIEVED LATER FOR USE IN CONJUNCTION WITH, E.G., HELMHOLTZ INTEGRAL PROBLEMS, HOLOGRAPHY AND SOUND FIELD RECONSTRUCTION PROBLEMS.
