Simulation Analysis of UAV Reconnaissance Effectin Complex Terrain Based on STK

为高效评估小型无人机对复杂地形区域侦察航路规划的合理性,提出采用STK(System Tool Kit,系统工具箱)软件对无人机(以美国RQ-7B“影子”无人机为例)侦察效果进行评估分析。首先,对目标区域实现完全区域覆盖及链路畅通条件进行理论分析;其次,利用STK软件计算分析无人机传感器对目标区域覆盖的特性,评估无人机与地面控制站的通信效果。仿真结果表明,STK可多角度分析、评估航线规划效果。计算结果准确、展示效果直观、操作简单快捷,可用于评估分析复杂地形条件下无人机航线规划方案的合理性,为无人机航线规划优化提供可靠有效的数据支撑。

In order to effectively evaluate the rationality of reconnaissance route planning for small UAV in complex terrain area,STK(System tool kit)software is proposed to evaluate the reconnaissance effect of UAV(taking RQ-7B"Shadow"UAV as an example).Firstly,theoretical analysis of the target area to achieve full area coverage and link unblocked conditions is carried out.Secondly,STK software is used to calculate and analyze the coverage characteristics of UAV sensors to the target area and the communication effect between UAV and ground control station.The simulation results show that STK can analyze and evaluate the effect of route planning from multiple angles,the calculation results are accurate,the display effect is intuitive,the operation is simple and fast,it can be used to evaluate and analyze the rationality of UAV route planning scheme under complex terrain conditions,and provide reliable and effective data support for UAV route planning optimization.
