摘要
图像导引头具有视场角度小,识别距离近的特点。为满足武器系统对目标截获概率的要求,需要设计导引头搜索方案以扩大导引头的视场范围。采用侧向一维搜索方案,可以减小搜索过程图像移动、变化对射手识别目标带来的不利影响;选择等角速度扫描与等线速度扫描两种扫描速度。对两种搜索方案进行仿真对比分析,仿真结果表明,设计的导引头搜索方案能满足搜索视场及停留时间的要求。
The image seeker had the characteristics of small field of view angle and short recognition distance.In order to meet the requirements of the target interception probability of the weapon system,the searching scheme of the seeker was designed to expend the field of view of the seeker.The lateral one-dimensional search method could reduce the adverse effects of image movement and change on target recognition in searching progress;the isometric angular velocity scan and the isometric linear velocity scan were selected.The two kinds of search schemes were simulated and compared,and the simulation results show that the searching scheme of the seeker satisfies both the demands of FOV of search and residence time.
