IRS/RIS启用的无人机通信系统的三种典型应用场景,即IRS-assisted UAV BS、IRS-mounted UAV relay和IRS-enabled UAV UE,如图所示。首先,无人机可以充当空中基站,而IRS通常放置在建筑物正面,以帮助重新配置无人机和地面用户之间的无线传播信道。无人机的机动性和IRS的可配置性为系统设计提供了更多的自由度。总之,mmW...
In this paper, we consider a novel hybrid reconfigurable intelligent surface (HRIS) consisting of active as well as passive reflecting elements mounted on unmanned aerial vehicle (UAV). The aim is to improve air-to-ground communication by assisting multiple users, while detecting several moving targ...

UAV-LS and ALS have the advantage of being mounted on moving platforms, thereby increasing the number of viewpoints as compared to TLS and potentially increasing canopy exploration. However, the upper canopy has a strong shielding effect that inhibits discovery of understorey (Brede et al., 2017...
The KF paradigm is then used to estimate and predict the propagation of wildfire based on local data obtained from a camera mounted on the UAV. This information is then used to obtain a safe path for the UGV that needs to travel from an initial location to the final position while the ...
The corresponding firmware and hardware system of the control system are also developed. The functional ground test shows that the control system meets the test requirements of the vehicle-mounted towed flight test.This is a preview of subscription content, log in via an institution to check ...
Intelligent reflecting surface (IRS) is composed of numerous passive reflecting elements and can be mounted on unmanned aerial vehicles (UAVs) to achieve six-dimensional (6D) movement by adjusting the UAV's three-dimensional (3D) location and 3D orientation simultaneously. Hence, in this paper, we...

Karst vegetation is of great significance for ecological restoration in karst areas. Vegetation Indices (VIs) are mainly related to plant yield which is helpful to understand the status of ecological restoration in karst areas. Recently, karst vegetation
Hyperspectral imaging is a powerful tool for remote sensing of vegetation and environment. Although unmanned aerial vehicles (UAVs) are increasingly utilized as a new platform for remote sensing, a conventional push-broom spectrometer is not suitable for
