| 摘 要： | 为了实现烟幕对激光制导武器有效的干扰,采用数值计算的方法,以布格-朗伯定律为数学基础,应用Vander Hulst近似计算方法,推导出了不同烟幕微粒参量对不同入射激光的干扰效果。数值计算结果表明,针对不同的激光波长,存在一个最佳的烟幕微粒参量,使对激光的干扰效果达到最佳。该研究对利用烟幕对激光制导武器实施有效干扰及干扰效果评估有重要的参考价值。

| Abstract: | By means of the approximate Vander Hulst numeration method,based on Bouguer-Lamber law,the effect of the smoke screens with different particles on the interference of different wavelength lasers was calculated.Numeric simulation indicated there was an optimum smoke particle parameter for a certain laser wavelength in order to obtain the best laser interference results.The study is valuable for both the evaluation and efficient interference on laser guidance weapon. |
