摘要

对商用无人机的螺旋桨、电机和机械臂进行了电磁仿真。目标是确定波浪的入射角,其中由于螺旋桨的位置导致结构的雷达横截面发生强烈变化,这将有助于多普勒分析。此外,无人机的测量使用商用的24 ghz FMCW雷达进行。我们考虑了两种情况:悬停和垂直移动。在这两种情况下,多普勒信号都是特征性的。

UAV detection with K band embedded FMCW radar
Electromagnetic simulations of a propeller, motor and arm of a commercially available UAV are presented. The goal was to identify the incidence angles of the wave where there is a strong variation of the radar cross section of the structure due to the position of the propeller, which will help in the Doppler analysis. Additionally measurements of the UAV were performed using a commercially available 24-GHz FMCW radar. Two scenarios were considered: hovering and vertical movement. In both cases the Doppler signature is characteristic.
