所设计的SGP-Ⅰ型旁视声呐具有两套工作频率Ⅰ)160千赫和190千赫;Ⅱ)25千赫和30千赫;它具有地质声呐和搜探声呐两种工作状态.本文第二部分介绍设计的通用精密多笔记录器,共有1024支(384+384+256)笔针,它有下列新特点:(1)电扫描方向可逆,故有七种工作方式.除用于双侧或单侧旁视声呐记录器外,也可作为其他水声设备精密记录器,还可以同时记录两种水声设备信号.(2)局部图象放大.可以扩展记录带宽11.5千赫的信号.(3)声速自动校正和声速数字显示.
The designed SGP-Ⅰ parallax sonar has two sets of operating frequencies: I) 160 kHz and 190 kHz; II) 25 kHz and 30 kHz; it has two working states: There are 1024 (384 + 384 + 256) stylus, which has the following new features: (1) Electro-scanning direction is reversible, so there are seven working methods. Except for double Side or unilateral sonar recorders, but also as other acoustic equipment, precision recorders, but also can record two kinds of underwater acoustic equipment signals. (2) local image amplification. You can expand the recording bandwidth of 11.5 kHz signal (3) Sound speed automatic calibration and sound speed digital display.
