职位描述
1、信号处理链路搭建:负责FMCW(调频连续波)雷达中频信号处理,包括CFAR(恒虚警检测)、DOA(到达角)估计、MIMO虚拟孔径成像,输出高保真的目标点云或微多普勒特征谱;
2、行为识别算法研发:针对家居复杂环境(多径效应、家具杂波),研发基于深度学习(GCN、Transformer、CNN)或传统机器学习的行为分类器,精准识别行走、静坐、挥手、摔倒(Fall)、跌倒后无法起身(Lying Post-Fall)等关键状态;
3、物理模型与AI融合(重点):借鉴模型驱动深度学习(Model-based Deep Learning)思想(如SubspaceNet类似架构),利用信号处理的物理先验(阵列流型、多普勒谱物理约束)引导神经网络训练,解决小样本及开集泛化难题;
4、时序行为分析与语义理解:基于连续帧的状态序列,构建行为语义理解模型,分析用户长期活动模式(作息规律、活动量),实现异常行为(如久坐、夜间离床过久)的主动预警;
5、边缘计算部署:将算法在嵌入式平台(TI/Skyrelay)进行轻量化优化与移植,确保家居产品的实时性与低功耗。
职位要求
1.硕士以上学历,雷达信号处理相关专业 有MIMO雷达/单基地/多基地雷达相关的项目课题或文章;
2.信号处理能力:精通 FMCW雷达测距/测速/测角原理,熟练掌握MIMO虚拟阵列设计与校准、DOA估计算法等;
3.点云与机器学习:熟悉点云基本处理(下采样、滤波、分割)及点云特征(例如:局部密度、速度分布、RCS);具有点云分类/动作识别经验,可独立实现基于传统特征(SVM/随机森林)或深度学习(PointNet、Transformer)的方案等;
4. 生理信号提取:熟悉利用毫米波相位/距离单元提取微小位移,掌握呼吸/心率的周期估计方法(FFT峰值搜索、小波变换、VMD等),能应对体动干扰下的鲁棒提取;
5. 工程能力:具备 C/C++ 基础,熟练使用 Python + NumPy/SciPy/scikit-learn 或 MATLAB 进行快速原型开发;了解嵌入式雷达芯片(TI IWR/AWR系列、NXP、Acconeer等)底层数据格式与实机调试。
