摘要：
The situation of researches on laser jamming to imaging detectors is analyzed and saturation effect of CCD under laser illumination is introduced. Combined with characteristics of CCD, diffraction limited point spread function (PSF) is applied to analyze the laser dazzled image and process of simulation is shown. Then simulated dazzled image is obtained and it is compared with actual image. With different laser powers, imaging performance parameters of simulated images are analyzed, such as Peak signal to noise ratio (PSNR), gray variation, definition, uniformity and so on. Experimental results show the feasibility and validity of laser jamming simulation. Moreover, changes of imaging performance parameters can provide useful references for further evaluation of laser jamming effect.
