外场激光导引性能分析

Analysis of Laser Guidance Performance in External Field

外场激光导引性能的测试分析是激光半主动制导武器科研试验中的重要环节,通过对激光半主动制导试验中从激光照射器-大气-目标-大气-导弹的光学传递链的分析和对激光大气传输特性和目标激光散射特性的研究,建立了从照射器到目标和从目标到探测器两个环节的照射激光能量传递模型,通过理论计算和外场试验实测数据,实现了对导引头入瞳处接收能量的计算分析,为外场激光导引性能分析提供了依据,具有较高的实用价值。

The analysis of laser guidance performance is an important link in the research of laser semi-active guided weapons.Based on the analysis of the optical transmission chain from laser target indicator-atmosphere-target -atmo- sphere-missile in laser semi-active guidance experiment and the study of the characteristics of the laser atmospheric transmission and the target laser scattering, the laser energy transfer model is established from the laser target indicator to the target and from the target to the detector .The calculation and analysis of the received energy at the entrance pupil of the seeker are carried out by the theoretical calculation and the measured data of the external field experiment, which provides the basis for the external field laser guidance performance analysis, and has high practical value and eco- nomic value.
