| 摘 要： | 采用偏振激光代替原来的激光脉冲进行水下目标探测，不但可以压缩回波信号的动态范围，减少水面回波的影响，同时不增加新的信息可探测性。本文研究地磁场和目标磁场对偏振激光的影响，并试图从中获得识别目标的参数。

| Abstract: | Using polarized laser in place of the pulse one to detect underwater target is of great advantages:the dynamic range of reflections and the influence of the reflected useless signals of the sea surface can be greatly depressed,at the same time,it includes more information about the target and enhances optical detectability.We demonstrate the influence of the magnetic field of underwater target/earth on the polarization of airborne laser in this paper and try to find a parameter to recognize the target. |
