| 针对传统无人机检测方法缺乏智能性和泛化性的问题，提出了一种基于权重不可知神经网络(Weight Agnostic Neural Network,WANN)的无人机微动特征检测方法，以实现探测无人机的目的。推导了旋翼无人机微动模型，详细说明了WANN模型的构建过程。以回波信号的循环谱等高图作为训练、测试数据集进行了仿真，结果表明该方法对噪声有较好的鲁棒性。实测结果也验证了WANN模型能有效提取无人机微动特征，有较好的图像识别能力。 |

| Abstract: |
| In view of the lack of intelligence and generalization of traditional unmanned aerial vehicle(UAV) detection methods,this paper proposes a UAV micro-motion feature detection method based on Weight Agnostic Neural Network(WANN) to achieve the purpose of detecting UAV.The micro-motion model of the rotor UAV is derived and then the construction process of WANN model is explained in detail.By using the cyclic spectral contour map of echo signal as the training and testing data set,simulation is performed.The results show that the proposed method is robust to noise.At the same time,the actual measurement results also verify that WANN model can effectively extract the micro-motion features of UAV and has a good ability of image recognition. |
