以电视制导**跟踪系统核心部件CCD导引头为研究对象，介绍了CCD的基本组成及工作原理。使用脉冲激光对KA-320 型面阵CCD进行了辐照实验，研究了脉冲宽度、峰值功率、重复频率对CCD饱和阈值的影响。使用Matlab中的Simulink工具对整个实验过程进行了仿真分析，从仿真结果归纳出脉冲激光对CCD探测器的干扰共性。最后得出结论：选用脉冲宽度小、峰值功率高、脉冲频率大的激光器更能使CCD导引头达到饱和，从而对制导**实施有效干扰。

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 was obtained that selecting a laser with narrow pulse width, high peak power and large pulse frequency will saturate CCD more easily, and thus can make effective jamming to guided weapons.
