Abstract
The report describes a research contract to develop the dry-end of an aocustic pulse repeater system referred to as CAPERS (Canadian Acoustic Pulse Echo Repeater System) for the Sonar Concepts and Applications Group of the Defence Research Establishment Atlantic. The system enables the re-transmission of an acoustic pulse simultaneously with the acquisition of the pulse. Additional pulses, including the acquired pulse and/or pre-defined pulses, may then be transmitted. It is possible to adjust the acoustic energy level and doppler shift of the transitted pulses. Acquired signals are stored to disk to later analysis. CAPERS is capable of pre-triggered signal acquisition, signal conditioning, signal re-transmission, as well as the corresponding control functions required to achieve this. The system has been developed using the LabVIEW programming environment, to operate on a Macintosh IIfx computer.
