摘要: 针对单元红外成像探测器的特点，利用激光的高亮度，对激光干扰单元红外成像探测器进行了理论分析和实验研究，研究了激光的功率参数和脉冲频率参数对单元红外成像探测器输出特性的影响，得到了具体的实验结果。并利用调制盘对激光脉冲的反射信号初步确定了单元红外成像探测器调制盘的旋转速度。Abstract: Since laser beam has great brightness and good orientation, there are more and more applications in the industrial and military fields. Based on the merits of laser, the laser jamming to the target acquiring and tracking system with modulator was studied by experiment and simulation. In these experiments, the key parameters of laser system are output power and the laser pulse frequency. The laser jamming mechanism was studied by changing the output power and pulse frequency. After the experiments, the detailed analysis was done and some valuable conclusions were made. And based on the laser pulse reflected from the modulator surface, the rotate speed of the modulator was determined.
