摘　　要：近年来,伴随着无人机技术的不断发展,我国民用无人机的市场规模正在逐年增长。随之而来的是无人机“黑飞”引发的一系列问题,这已经成为影响社会安全的重大问题。本文对无人机跳频通信信号检测展开研究,提出了一种针对无人机跳频通信信号的检测方法。根据无人机跳频通信信号帧带宽的短时稳定特性,使用短时傅里叶变化结合带宽和中心频率匹配法来估计无人机跳频通信信号帧的带宽、中心频率和持续时间。再结合跳频通信具有的周期性来判断是否存在无人机跳频通信信号。In recent years,with the continuous development of drone technology,the market size of civil drones in China is increasing year by year.Along with it comes a series of problems caused by drone"black flying",which has become a major issue affecting social security.This article conducts research on the detection of drone frequency hopping communication signals and proposes a detection method for drone frequency hopping communication signals.Based on the short-term stability characteristics of the bandwidth of the drone frequency hopping communication signal frame,the bandwidth,center frequency,and duration of the drone frequency hopping communication signal frame are estimated using a combination of short-term Fourier transform and bandwidth and center frequency matching method.Combined with the periodicity of frequency hopping communication,determine whether there is a drone frequency hopping communication signal.
