摘要
文章介绍了利用非线性声学原理和声纳测距原理测量海冰上下界面信息的技术和方法,并根据海冰的声学特性计算海冰的厚度。
To measure the water-ice and ice-air interface of sea ice, a technique and a method are introduced with non-linear acoustics theory and sound ranging, and the thickness of sea ice can be gotten according to the sound characteristics of sea ice.
