摘    要:理论分析了激光干扰调制盘型点源跟踪系统敏感参数。根据理论分析结果:结合近场和外场到达点源跟踪系统处目标、干扰激光辐射功率密度等效原则,设计和进行了不同激光功率、外调制频率、外调制占空比和重复频率下激光干扰点源跟踪系统光学锁定断开近场模拟实验。理论分析和实验结果均表明:干扰激光功率、外调制频率和外调制占空比是实现调制盘型点源跟踪系统光学锁定断开的关键参数;干扰激光重复频率与调制盘载频没有严格对应关系,干扰激光重复频率和占空比应满足激光器最佳工作状态,以提高干扰激光功率。本文对小功率激光干扰系统设计研制和试验开展具有重要参考意义。

关 键 词:激光干扰  调制盘  点源红外跟踪系统  光学锁定断开

Abstract:The sensitive parameters of laser jamming infrared point guided seeker were analyzed at first in this paper.According to the radiation power density equivalence principle of tracing target and laser interference system at the infrared point guided seeker under infield and external field,the experiments were designed.Then,the verification experiments of various power,different external modulation frequencies,and different external duty-ratio and repetition rates of jamming laser were carried out.Both theoretical analysis and experimental results show that,the power,external modulation frequency and external duty-ratio are sensitive parameters.There is not strict connection between repetition rates of jamming laser and carrier frequency of reticle.The repetition rate and external duty-ratio of jamming laser should be the optimal set to increase power.The research is useful for the laser jamming system design.It also can be applied to laser jamming infrared point guided seeker external field test.
Keywords:laser jamming  reticle  infrared point guided seeker  optics tracking loss
