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。

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.

当它的确切范围被划分后，一个定向能武器专家Doug Beason，把它放在700米，而波束不能穿透一些材料，如铝。

While its exact range is classified, Doug Beason, an expert in directed-energy weapons, puts it at about 700 meters, and the beam cannot penetrate a number of materials, such as aluminum.
