There's probably more than one way to accomplish this, but you'll do it by mounting a sonar sensor on the robot's left side.
有多种实现这一目标的方法，但是我们采用的方法是在机器人的左边安装一个声纳传感器。
Note: Do not place the sonar sensor directly on an icy surface, cut a whole in the ice first and then place the sonar in the water.
注意：不要将声纳传感器直接放在冰面，先在冰面上凿开一个洞，然后放置在水中。
The orientation of the sonar beam was considered in the active dipping sonar sensor model to complete the target movement analysis such as differentiating orientation.
在主动式吊声模型中，考虑声纳的波束方向，便于对目标进行定向等运动分析。
