针对复杂城市环境中低空慢速小型无人机探测难题,本研究提出一种基于信道冲激响应高阶统计特征的无源探测方法。该方法通过构造接收信号的Hankel矩阵,基于奇异值分解,分析常态环境下以及无人机入侵下的接收信号分布规律,通过构造残差矩阵实现强静态背景与弱动态目标信号的分离。在此基础上引入高阶累积量计算,弱化噪声对信号的影响,通过方差量化无人机运动引起的统计非平稳性。仿真结果表明,在低速运动状态下,含无人机场景的高阶累积量方差相较于常态环境时,会产生显著的系统性抬升和波动。研究证实,融合奇异值分解与高阶累积量方差监测的联合检测框架,能够在低信噪比条件下有效提取无人机对信道的高阶统计扰动,为无人机的探测提供了新的技术途径。
Aiming at the challenge of detecting low-altitude
slow-moving
and small unmanned aerial vehicles in complex urban environments
this study proposes a passive detection method based on higher-order statistical features of channel impulse responses. The method constructs a Hankel matrix from the received signals and utilizes singular value decomposition to analyze the distribution patterns of received signals under normal conditions versus those during UAV intrusion. By constructing a residual matrix
it achieves the separation of strong static background signals from weak dynamic target signals. On this basis
higher-order cumulant computation is introduced to mitigate the influence of noise on the signal
and the statistical non-stationarity induced by UAV motion is quantified through variance. Simulation results demonstrate that under uniform motion conditions
the higher-order cumulant variance in UAV-present scenarios exhibits a significant systematic elevation and fluctuation compared to that in normal environments. The study confirms that the joint detection framework integrating singular value decomposition and higher-order cumulant variance monitoring can effectively extract the higher-order statistical disturbances of the channel caused by UAVs under low signal-to-noise ratio conditions
providing a new technical pathway for UAV detection.
