A Towed, Multi-Frequency H.F. Sonar System for Scattering and Ocean Dynamics Studies.

Abstract

The system described provides wide operational flexibility at any operating frequency from 5 kHz to over 800 kHz (except for a small band around 455 kHz) limited mainly by the availability of transducers. Variable pulse width, variable receiver bandwidth, low receiver noise, various time variable gain functions and wide system dynamic range characterized the system. Built-in time-sharing controls maximize flexibility of graphics display on either dry-paper or fiber-optic CRT recorders. (Author)
