Platform Electronics for a Short Baseline Acoustic Position Measurement System

摘要

The interim report was prepared to consolidate the detail design of platform electronics for a short baseline acoustic position measurement system. The design is suitable for use with a variety of insitu geometries using either passive reflectors, transponders or ocean floor arrays. The platform electronics complement divides into four general areas; that of signal generation and reception, signal processing, range computation and coordinate generation. The first two areas make use of analog circuitry, i.e., amplifiers, filters, etc., whereas the latter two areas are composed primarily of digital equipment. The discussion treats each area individually, prefaced by a general system description and followed by the equipment installation requirements. (Author)
