摘要

对低空目标的有效管控是推动低空

经济发展的关键。城市环境中强杂波和建筑物遮挡等因素使得传统雷达探测手段难以实现对低速无人机的有效监测。基于此，提出了一种无人机探测的新思路，即通过识别信道状态特征的变化来判断无人机是否出现在指定区域。该方法的核心在于利用城市中已广泛部署的移动基站等外辐射源，基于K-Medoids聚类算法捕捉无人机出现后对原有多径信道路径数量的影响，从而实现对无人机的感知。该方法不需要构建精确的参考信号，也不需要利用多普勒体制抑制强杂波。仿真结果表明，所提方法在1 km

范围内能实现80%以上的检测概率，且随着范围缩小，检测概率能达到90%左右，因此能够在城市场景下有效探测低空慢速无人机。

Abstract

Effective management of low-altitude targets is key to promot the development of the low-altitude economy. In urban environments

strong clutter and building occlusion make it difficult for traditional radar detection methods to effectively monitor low-speed drones. Based on this

a new approach of drone detection was proposed

which involved identifying changes in channel state characteristics to determine whether a drone was presented in a specified area. The core of this method lied in utilizing the already widely deployed mobile base stations and other external radiation sources in cities

capturing the impact of drone presence on the number of multipath channel paths by using the K-Medoids clustering algorithm

to achieve drone perception. This method did not require the construction of an accurate reference signal nor the use of Doppler systems to suppress strong clutter. Simulation results show that the proposed method can achieve detection probabilities of over 80% within a range of 1 square kilometer

and the detection probability can reach about 90% as the range decreases. Therefore

it is capable of effectively detecting low-altitude

slow-moving drones in urban scenarios.
