摘要

本文给出了微型无人机旋翼叶片电磁散射的仿真和实验结果。这项工作的重点是研究这些反射的变化作为诸如偏振、频率和方位角等变量的函数。仿真结果清楚地表明,散射随方位角和频率的变化很大。对这些变化进行了实验验证,并发现了方位角的类似趋势。本文给出了一架可操作微型无人机在不同偏振下的多普勒分量,这些多普勒分量显示了实际雷达系统接收到的预期信号。

Micro-drone RCS analysis
This paper presents both simulation and experimental results of micro-drone rotor blade electromagnetic scattering. The focus of this work is investigating the variation of these reflections as a function of variables such as polarization, frequency and azimuth angle. The simulation results clearly show a strong variation in scattering with azimuth and frequency. Experimental validation of these variations was investigated and similar trends in azimuth were found. The Doppler components from an operational micro-drone in varying polarizations are shown, these demonstrate the expected signals received by a real radar system.
