6个典型操作场景
6.1鱼类回声
6.1.1 DSTS-5A/2C能够在表面之间产生二次回波
和底部。该回波可用于模拟鱼或其他物体的回波
位于底部上方，将被称为鱼类回声。深度、持续时间和
可以设置鱼回声的拱形。鱼类回声的持续时间由
指定鱼经过海底时将产生的回声数量
传感器。通过指定深度可以生成更真实的鱼类回声
定期的加薪鱼类回声的深度减少了一半
在剩余的时间里增加。如果增量设置为零，则鱼
回声在持续时间内将保持在恒定深度。
6.2设置典型的鱼类回声
6.2.1通过键入“d250‘enter’”将底部深度设置为25英尺。将鱼的深度设置为23
通过输入“D230‘回车’”来调整脚。通过输入20个脉冲的时间
“e20‘输入’”。通过输入“E3‘输入’将鱼的时间设置为3个脉冲”
6 TYPICAL OPERATING SCENARIOS
6.1 FISH ECHO
6.1.1 The DSTS-5A/2C is capable of generating a secondary echo between the surface
and bottom. This echo can be used to simulate an echo from a fish or other object
above the bottom and will be referred to as a fish echo. The depth, duration and
arch shape of the fish echo can be set. The duration of the fish echo is set by
specifying the number of echoes that the fish will generate as it passes under the
transducer. A more realistic fish echo can be generated by specifying a depth
increment. The depth of the fish echo is decreased for half the duration then
increased for the remainder of the duration. If the increment is set to zero the fish
echo will remain at a constant depth for its duration.
6.2 SETTING UP A TYPICAL FISH ECHO
6.2.1 Set the bottom depth to 25 feet by typing “d250 'enter'”. Set the fish depth to 23
feet by typing “D230 'enter'”. Set the fish echo off time to 20 pulses by typing
“e20 'enter'”. Set the fish on time to 3 pulses by typing “E3 'enter'”
