高重频激光压制干扰与激光制导系统相互作用效应研究

在时域上分析了高重频激光压制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,采用二极管泵浦全固体高重频激光器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高重频压制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,说明高重频激光压制干扰与激光制导系统相互作用效应表现为激光导引头的信息处理机制被破坏,不能正常给出的水平、俯仰角度误差信息,但这种破坏在压制干扰消除后即刻消除.

Interactional effect between a suppressive laser jammer with high frequency and a laser guidance system

The signal process of a laser seeker was analysed on time domain when it was interfered by a suppressive laser jammer with high frequency. A laser guidance system with countermeasures acting as an interfered target and a high-frequency diode-pumped solid state laser 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 characterizing the interactional effect, although they show that the information processing mechanism of the laser seeker is damaged when the seeker receives high frequency laser signals so the seeker can not provide the angle errors of azimuth and elevation, the phenomena are disappeared when the suppressive jamming is removed.
