Abstract:
Design approach for improved system performance of a microprocessor controlled sonar buoy performing surveillance of underwater objects is proposed. When launched into sea or ocean the microprocessor controlled buoy sets into action for automatic scanning of the underwater as to extract the object information and transmit the same by wireless to a remote ground station for further processing and taking final control action. System design outline for sonar buoy incorporating 11-cell replica correlation resulting in improved system performance is presented in this paper. Although the complexity of the hardware replica correlator is minimized using the recent digital delay lines the proposed microprocessor controlled buoy performs replica correlation through software and extracts object information conceding improved system performance.
