【摘要】：利用自行设计的0.53和1.06μm双波长复合输出激光器,对复合激光干扰COMS相机和激光半主动(SAL)制导系统的效能进行了实验评估。在CMOS相机干扰实验中,分析了复合激光连续和5kHz高重频输出时的干扰效果;分别在有无激光防护两种情况下,对比了复合激光与单波长激光的有效干扰面积曲线。结果表明,存在激光防护措施时,复合激光的有效干扰面积较单波长激光干扰提升显著,其有效干扰面积分别最大增加67.0%和53.1%。在SAL制导系统干扰实验中,对比了导引头在复合激光和0.53μm波长激光干扰下的预处理信号波形。结果表明,高重频复合激光能有效扰乱导引头的预处理信号,使其波形相关度最大降低25.1%,干扰效果较0.53μm波长激光提升显著。
[Abstract]:The self-designed dual-wavelength compound output lasers of 0.53 and 1.06 渭 m are used. The effectiveness of the hybrid laser jamming COMS camera and the laser semi-active SAL) guidance system is evaluated experimentally in the CMOS camera jamming experiment. The interference effect of continuous and 5kHz laser output is analyzed. With or without laser protection, the effective interference area curves of composite laser and single wavelength laser are compared. The results show that there are laser protection measures. The effective jamming area of the composite laser is significantly higher than that of the single wavelength laser, and the effective jamming area of the composite laser is increased by 67.0% and 53.1 respectively. In the jamming experiment of SAL guidance system. The waveforms of the preprocessing signal of the seeker under the interference of compound laser and 0.53 渭 m wavelength laser are compared. The results show that the high repetition laser can effectively disturb the preprocessing signal of the seeker. The maximum correlativity of the waveforms is reduced by 25.1.The interference effect is significantly higher than that of the 0.53 渭 m wavelength laser.
