摘要
在激光引信中,脉冲激光对目标的探测与识别是激光引信近程探测技术中的一个关键技术点,而目标的表面反射特性对探测的影响是激光近程探测高效毁伤与精确打击目标的主要研究关键。目标的表面粗糙度以及附着物对激光回波信号的强弱影响较大,因此,需对激光近程探测过程中不同粗糙度目标表面所表现的反射特性进行研究。首先通过仿真得到回波信号模型,再进行不同粗糙度表面回波功率实验对仿真结果进行验证。实验选用不同表面粗糙度的靶板,并采用了改变角度、改变距离并同时改变角度和距离的模式来观测得到的电压曲线,获得最终结果。
In laser fuze, target detection and recognition by pulse laser is a key technical point in laserfuze short-range detection technology, and the influence of the target＇s surface scattering properties ondetection is a major research key in efficient damage and precise strike on targets through laser short-range detection. The target＇s surface roughness and the attachment largely influence the strength of laserecho signal. Therefore, it is necessary to study the scattering properties shown by target surfaces withdifferent roughness during laser short-range detection. Firstly, echo signal model was obtained throughsimulation, and then echo power experiment on surfaces with different roughness was carried out to verifythe simulation results. In the experiment, target plates with different surface roughness were used, andmethods such as changing the angle, changing the distance, etc., were adopted to observe the voltagecurve, thereby obtaining the final result.
