摘要

近年来，基于毫米波雷达的脚踢动作识别作为一种免手操作的人机交互技术，在智能家居和车载应用等领域展现出重要应用价值。然而，复杂环境下的静态干扰（如墙壁、石柱及天线耦合干扰）和动态干扰（如行人运动、肢体微动）仍对识别精度构成挑战。为实现高精度、稳健识别，提出一种融合干扰抑制与深度学习的识别方法。该方法通过向量均值相消与动目标显示（moving target indication，MTI）抑制静态干扰，并结合多普勒加权、恒虚警率（constant false alarm rate，CFAR）检测、密度聚类（density-based spatial clustering of applications with noise，DBSCAN）以及连通域约束消除动态干扰。随后，提取多帧距离-多普勒图（range-Doppler map，RDM）和距离-角度图（range-angle map，RAM）作为模型输入，构建基于卷积神经网络（convolutional neural network，CNN）、多头自注意力（multi-head self-attention，MHSA）以及简化时序卷积网络（simplified temporal convolutional network，STCN）的双流CNN-MHSA-STCN模型，用于完成动作识别。实验表明，该方法在自采数据集上的识别精度超过98%，在复杂环境中具备较高的精度与鲁棒性。

Abstract

In recent years

millimeter-wave radar-based kick motion recognition has attracted significant attention as a hands-free human-computer interaction technology

demonstrating considerable value in applications such as smart home systems and automotive interfaces. However

in complex environments

both static interference (e.g.

walls

pillars

and antenna coupling effects) and dynamic interference (e.g.

pedestrian movements and subtle limb motions) continue to present substantial challenges to recognition accuracy. To achieve high-precision and robust recognition

an integrated method combining interference suppression and deep learning was proposed. The method employed vector mean cancellation and moving target indication (MTI) to suppress static interference. In contrast

dynamic interference was mitigated through a combination of Doppler weighting

constant false alarm rate (CFAR) detection

density-based spatial clustering of applications with noise (DBSCAN)

and connected region constraint. Subsequently

multi-frame range-Doppler maps (RDM) and range-angle maps (RAM) were extracted to serve as model inputs. A dual-stream CNN-MHSA-STCN architecture was constructed

incorporating a convolutional neural network (CNN)

multi-head self-attention (MHSA)

and a simplified temporal convolutional network (STCN) for comprehensive motion recognition. Experimental results demonstrate that the proposed method achieves a recognition accuracy exceeding 98% on a self-collected dataset

while maintaining high precision and robustness in complex operational environments.
