激光欺骗式干扰与激光制导系统相互作用效应研究

在时域上分析了激光欺骗式干扰作用时,激光导引头的信息处理过程.以具有抗干扰措施的激光制导系统为干扰目标,采用转发式激光欺骗干扰设备为干扰源干扰激光导引头,通过外场试验从系统级角度研究了欺骗式干扰与激光制导系统相互作用效应.用所记录的目标视线和系统光轴角误差数据表征相互作用效应,说明激光欺骗式干扰对激光导引头的影响与干扰设备的激光输出功率、欺骗信号的特性、外界环境因素以及激光导引头的信息处理方式密切相关.

INTERACTIONAL EFFECT BETWEEN LASER CHEATING JAMMER AND LASER GUIDANCE SYSTEM

The signal process of a laser seeker was analysed on time domain when it was interfered by a laser cheating jammer.A laser guidance system with countermeasure acting as an interfered target and a laser cheating jammer acting as an interfering source,the interactional effect between them was tested from the view of systems on field.The angle errors between the sight of target and the optical axial of a laser seeker were used to characterize the interactional effect.The results show that the effect of a laser cheating jammer on a laser seeker closely relates to the output power of the jammer and the performance of the cheating signal and environmental elements and the methods of signal processing of a laser seeker.
