【摘要】 提出了激光引信环视扫描成像探测新方法,其原理是探测目标表面反射回波,是主动探测方式。该方法成像独特,利用弹目交会过程中的周向扫描和相对高速运动,使目标各部位依次进入和退出探测视场来完成对目标各部位成像探测。通过目标回波功率和图像边缘弱化的计算,获得目标二维形体图像。以后对图像进行处理,识别出目标易损部位并输出弹目交会信息作为引爆控制信号,对战斗部实施定向起爆控制,以精确打击目标。仿真结果表明,该成像探测方法及所建仿真模型是正确有效的。更多还原

【Abstract】 A new detection method by circle-scan imaging in laser fuze is proposed. Its principle is to recognize target by actively detecting the returning echo signal of different part of target. This method is applied to laser fuze because of the special and effectual character of the imaging. That is to say, during engagement of missile and plane, as various parts of plane enter and exit the detector’s field of view in turn, the imaging detection of different parts of target can be achieved through circumferential scanning and relative high-speed motion. By computing the power of the target returning echo and image edge weakness, a 2-D image of target shape feature is obtained. The vulnerable positions of a target can be recognized through processing the image of a target. The missile-target engagement information can be exported and used as detonator control signal for directional explosion of the payload so as hitting targets accurately. The simulation results show that the imaging detection method and the constructed simulation model are correct and feasible.更多还原
