摘要: 详细讨论了海水作为激光传输信道的基本特点,在此基础上提出了等相位体的概念,分析了等相位体的形状,并且研究了等相位体背向散射强度的估算方法,为利用伪随机序列进行水下测量或通讯获得的资料估算散射强度提供一种方法.Abstract: The basic properties of the seawat erare discussed as the laser transmitting channel, based on these properties the concept of equal phase volume is proposed, the shape of it is analyzed, and the estimating calculation method of the backscattering intensity of it is studied.It provides an estimating method in underwater measurements or communications by means of pseudo random sequence.
