摘要

开展了多波段激光(750~970 nm)对彩色CCD成像系统的外场干扰实验

测得了不同辐照条件下对外场1.3 km处彩色CCD成像系统的干扰效果;建立了彩色CCD相机的激光干扰模型

对实验结果进行了理论验证与分析。理论与实验结果表明:强激光对彩色CCD成像系统的干扰效果明显

CCD靶面出现了明显的光饱和和串扰现象

光饱和区域的形成是由激光束进入光学系统后发生衍射效应造成的;到靶激光功率密度越强

CCD靶面光饱和面积越大

激光干扰效果越好;单波段750 nm激光作用下

到靶功率密度为4.2 kW/cm

CCD靶面的光饱和面积为0.88 mm0.97 mm;多波段激光(750~970 nm)作用下

到靶功率密度为20.7 kW/cm

CCD靶面发生全靶面饱和现象;仿真结果与实验结果基本一致

证明了理论模型的正确性。对远场干扰能力计算结果表明:随着干扰距离的增加

到靶功率密度减小

激光干扰效果变差。

Abstract

Out-field laser jamming experiment of single CCD colour imaging system irradiated by multi-wavelength laser (750-970 nm) was done. Laser jamming effects of colour CCD imaging system with different irradiating conditions were measured at 1.3 km. Laser jamming model was set up

and theoretical proving and analysis on experimental results were completed. Theoretical and experimental results show that the jamming effect of laser on colour CCD imaging system is obvious

CCD surface appears obvious light saturation and crosstalk phenomena. The light saturation phenomenon is caused by laser diffraction effect. In addition

laser jamming effect and light saturation gradually enhance with the increasing of the laser power density to target. When the laser power density to target of single wavelength 750 nm laser is 4.2 kW/cm

the light saturation area of CCD surface is 0.88 mm0.97 mm. When the laser power density to target of multi-wavelength laser is 20.7 kW/cm

CCD device appears the whole target saturation. The simulation results are coincident with the experimental results

and it proves that the laser jamming model is correct. The simulation results for far-field laser jamming show that the laser jamming effect gradually weakens with the increasing of laser jamming distance.
