Paper Abstract

The paper presents principles and design considerations of optoelectronic multi-module spectrum analyzers (direction finders) for fast processing of coherent acoustic signals. The results of theoretical investigations are discussed and the module design is considered for the systems implementing both amplitude-only and amplitude/phase processing of coherent low- frequency signals by means of radial and turn shearing interferometers.
