中文摘要：

对＂全球鹰＂无人机成像侦察载荷能力进行了分析与仿真。首先,总结＂全球鹰＂无人机侦察载荷的发展历程;其次对＂全球鹰＂载光电、红外、SAR 3种侦察设备以及MP-RTIP雷达进行了介绍;最后采用STK（Satellite Tool Kit）软件建立相应的场景,对＂全球鹰＂侦察能力进行可视化仿真设计,得出在同一航线条件下,不同传感器对固定区域的平均覆盖比率不同;仿真结果表明,＂全球鹰＂无人机采取的侦察航线会对传感器的工作效果产生影响,在作战中,要根据战场实际情况选择合适的传感器。

英文摘要：

This article analyzes and simulates the imaging reconnaissance equipment capacity of Global Hawk UAV. Firstly,the development of reconnaissance equipment is summarized. Then,the reconnaissance equipment including EO,IR,SAR and MP-RTIP are introduced. Finally,the simulation situation is established with STK. Because of visualization simulation design,it is summarized that the average coverage ratio of fixed area is different with various sensor. Simulation results show that the reconnaissance route can affect effect of sensor. So suitable sensor should be elected in battle based on the battlefield situation.
