Research abstract
THE REQUIREMENTS OF SPREAD SPECTRUM TECHNOLOGY, ACOUSTIC COMMUNICATION, AND SIGNAL SPECTRUM CODING MAKE IT NECESSARY TO INCREASE THE EFFECTIVE BANDWIDTH OF THE SONAR PROJECTOR. A UNIQUE APPROACH TO DOING THIS WITHOUT SACRIFICING THE TRANSMITTING AND RECEIVING RESPONSES OR TOTALLY REDESIGNING THE TRANSDUCER, IS TO APPLY THE TECHNIQUE OF NEGATIVE IMPEDANCE. THE MAJOR GOALS OF PHASE I WILL BE TO (1) SHOW THE FEASIBILITY OF USING A NEGATIVE IMPEDANCE DEVICE TO SIGNIFICANTLY INCREASE THE BANDWIDTH OF AN OPERATIONAL SONAR PROJECTOR, AND (2) TO GENERATE THE DESIGN AND TEST SPECIFICATIONS OF THAT DEVICE FOR EVALUATION IN PHASE 2. THE TECHNICAL TASKS INCLUDE A TECHNOLOGY REVIEW OF NEGATIVE IMPEDANCE AMPLIFIERS, A DETAILED COMPUTER SIMULATION AND PARAMETRIC ANALYSIS, AND THE DESIGN OF A NEGATIVE IMPEDANCE DEVICE TO WORK WITH A SPECIFIC PROJECTOR AND DRIVER AMPLIFIER.
