摘要:

螺旋桨调制,又称微多普勒调制,对无人机执行的射频(RF)检测作业构成重大挑战。本文研究RF信号上螺旋桨调制效应的均衡,专门针对仪表着陆系统(ILS)等导航辅助设备的应用。通过采用连续参考音调,可以有效捕获并均衡螺旋桨诱导的多普勒扩展,从而提高信号完整性与准确性。仿真结果表明,所提出的均衡方法显著降低了螺旋桨调制引起的DDM偏差,即便在不同螺旋桨转速下也是如此。研究结果表明,引入此类均衡技术可以提升基于无人机的RF检测的可靠性与效率。

英文摘要:

Propeller modulation, also known as micro-Doppler modulation, presents a significant challenge in radio frequency (RF) inspection operations conducted via drones. This paper investigates the equalization of propeller modulation effects on RF signals, specifically targeting applications in navigation aids such as Instrument Landing Systems (ILS). By employing a continuous reference tone, the propeller-induced Doppler spread can be effectively captured and equalized, improving signal integrity and accuracy. Simulation results demonstrate that the proposed equalization method significantly reduces DDM deviation caused by propeller modulation, even under various propeller speeds. The findings suggest that incorporating such equalization techniques can enhance the reliability and efficiency of drone-based RF inspections.
