摘要
从应用于尾流自导角度出发,在实验基础上提出了一种利用尾流中气泡对激光的后向散射光特性探测舰船的新方法。一般情况下,在不考虑水面波动的条件下能得到明显的气泡后向散射光信号;当有波浪存在时,后向散射光信号则不明显。对此本文提出了利用气泡的后向散射光接收信号与波动水面反射信号在频域的差异判别气泡存在的方法,计算表明,采用这种方法可以达到较好的判别效果。
Aiming the application to torpedo wake homing, a new method is presented to detect warships based on the laser back scattering characteristic of wake bubbles. The experimental results demonstrate that the laser back scattering signal of bubbles without water surface fluctuation is quite intense, while the back scattering signal becomes faint if water surface fluctuation exists. By analyzing the two different scattering signals , it is discovered that they have different characteristic in frequency domain. The calculation proves that this difference can be effectively used detect bubbles.
