基于激光主动探测的“猫眼效应”研究

 针对基于“猫眼效应”的激光主动探测技术在光电对抗中的广泛应用，建立了迎面观瞄光电装置光学系统反光指数数学模型，并结合探测组件建立了探测距离数学模型，模拟了反光指数与内部特性参数间的数值关系及探测距离与迎面观瞄光电装置主要参数间的数值关系。为了验证建立的数学模型的正确性，利用研制的激光主动探测装置，分别以2.5 mm、5.5 mm孔径角镜和25 mm、35 mm、56 mm孔径光电观瞄装置为目标，进行了最大探测距离模拟和验证实验，模拟值分别为1 290 m、1 656 m、866 m、1 919 m、1 226 m，实验值分别达到1 100 m、1 500 m、800 m、1 800 m、1 200 m。结果表明：最大探测距离模拟值和实验值有很好的一致性。

Cat's-eye effect based on active laser detection

Aiming at the extensive application of the active laser detecting based on “cat-s-eye effect” in electro-optic counterreconnaissance, we built the mathematic model of the optic-echo index for the head-on sight electro-optic equipment and the mathematic model for detecting range combined with the detecting components, simulated the numerical value relation between the optic-echo index and the internal characteristic parameter, and the one between the detecting range and the primary parameter for the head-on sight electro-optic equipment- In order to verify the mathematic model-s correctness，taking the 2.5 mm,5.5 mm aperture cat-s-eye retroreflectors and the 25 mm,35 mm,56  mm aperture sight electro-optic equipments as the targets, and the active laser detection equipment as the detecting system, we conducted maximum detecting distance simulation and verification tests, the analogue detecting ranges were 1 290 m,1 656 m, 866 m, 1 919 m and 1 266 m, respectively, the maximal detecting ranges were 1 100 m,1 500 m, 800 m, 1 800 m and 1 200 m, respectively. The result demonstrates that the analog numerical values are accordant with the test numerical values for the maximal detecting ranges.
