The CCD seeker is the key part of the tracking system for TV guided weapons.The basic composition and working principle of CCD are introduced.Jamming experiments of KA-320 CCD were made under irradiation of pulse laser.The effects of pulse width,peak power and repetition rate of the laser on CCD detector's saturation threshold were studied.Simulation was carried out by using Simulink of Matlab,and the feature of pulse laser's jamming to CCD detector was concluded from the simulation results.The conclusion w...
