摘要： A side-scanning sonar towfish constructed from a solid polyvinyl chloride (PVC) rod is provided. The PVC rod is milled and slotted to provide recesses for electronics and transducers and slotted to provide attachment points for fins and tow rail. The entire fish is then filled and sealed with urethane thereby providing sealed solid unit. A special multi-layer acoustic matching system is bonded over the transducers to provide maximum coupling efficiency of the acoustic signal thereby allowing operation of the fish at reduced power requirements.

摘要： In order to obviate the necessity for providing a complete channel of electronics for each transducer of an array incorporated into a real-time ultrasonic imaging system, all system transducers are disposed in apparent series with a single inductor as to direct current. Charging resistors permit each transducer to slowly capacitively charge to a predetermined voltage under static conditions. When a switching transistor disposed in series with a given transducer is placed in the conducting state, the transducer rapidly discharges and mechanically deflects to introduce an ultrasonic pulse into an object. While the switching transistor remains conductive, the inductor and transducer are in parallel circuit as to echo signals returning to the transducer. When the switching transistor is rendered non-conductive, the transducer again charges capacitively in anticipation of a succeeding cycle. All echo signals sensed are amplified by a single preamplifier and applied to a display which is sweep coordinated with the sequence of transducer energization.
摘要翻译：为了避免为并入到实时超声成像系统中的阵列的每个换能器提供完整的电子通道的必要性，所有系统换能器与直流电流的单个电感器呈明显的串联布置。充电电阻允许每个换能器在静态条件下缓慢地电容充电到预定电压。当与给定换能器串联布置的开关晶体管置于导通状态时，换能器快速放电并机械偏转以将超声波脉冲引入到物体中。当开关晶体管保持导通时，电感器和换能器与返回到换能器的回波信号并联。当开关晶体管变得不导通时，换能器再次以电容性进行充电以预期随后的周期。感测到的所有回波信号由单个前置放大器放大并应用于与传感器通电序列扫描协调的显示器。

摘要： A microcomputer-based side scanning sonar system is provided. The system uses a personal microcomputer with a custom designed control and data collection circuit card to provide integrated sonar and navigational data to a display. A specialized software program allows navigational data to be collected from any standard navigational device compatible with NMEA 0183 standards and integrated with sonar data. The system allows accurate and repeatable navigation to sonar targets, including return to the target.
