利用自身携带的侦察设备对大区域内目标进行独立的侦察是无人机在现代战场上的主要应用之一.针对无人机执行侦察任务的效能问题,首先,建立了CCD摄像机的侦察模型,在分析了无人机完成侦察任务的能力和侦察代价后,提出了大区域侦察路径的效能评价模型;接着,应用效能评价模型,对无人机的光栅式侦察方式进行了改进及路径分析,并通过仿真进行了验证.研究结果对无人机完成实际的侦察任务具有一定的参考作用和工程应用价值.

To reconnoiter targets in a large-scale area independently with onboard reconnaissance equipment was one of the most important applications for UAVs in modern battle field.Focusing on the problem of effectiveness evaluation for UAV when executing reconnaissance tasks,a model was built up for CCD camera,and the advantages and the disadvantages of UAVs in excuting reconnaissance were analyzed.Based on which a model was proposed for evaluating large-range reconnaissance route planning.Then,using this model,the searching pattern of UAV,box-spiral,was improved and the path was analyzed.The improved pattern was verified by a simulation.The effectiveness evaluation model and the improved searching pattern can be taken as a reference for UAVs in taking reconnaissance tasks,which has certain engineering values.
