一种低空遮挡场景感知增强方案研究OA

With the steady and rapid growth of low altitude unmanned aerial vehicle business,the integration of sensing and communication for low airspace scenarios has become an essential key in the development of low airspace economy.The use of existing 5G base stations for low airspace integrated communication and sensing has also become a research hot-spot.For the blockage problem in low airspace sensing,this paper proposes to use an Reconfigurable intelligent surface and edge to improve sensing performance,and proposes a performance evaluation framework to analyze the performance of different sensing methods and electromagnetic manipulation devices.Simulation shows that the addition of electromagnetic control mechanism can effectively improve the sensing probability of unmanned aerial vehicles in the low airspace scene.At the same time,the passive sensing method is superior to the active one,and the performance of the diffraction enhancement structure is also better than that of reconfigurable intelligent surface.
