Abstract

The design and implementation of a real-time passive high Doppler resolution radar system is described in this paper. Batch processing and pipelined processing flow are introduced for reducing the processing time to enable real-time display. The proposed method is implemented on a software defined radio (SDR) platform. Two experiments using this system are described: one based on small human body motions and another one on hand gesture detection. The results from these experiments show that the proposed system can be used in a range of application scenarios such as eHealth, human-machine interaction and high accuracy indoor target tracking.

实时高分辨率无源WiFi多普勒雷达及其应用
介绍了一种实时无源高多普勒分辨率雷达系统的设计与实现。为了减少处理时间,实现实时显示,引入了批处理和流水线处理流程。该方法在软件定义无线电(SDR)平台上实现。介绍了该系统的两个实验:一个是基于人体微小运动的实验,另一个是基于手势检测的实验。实验结果表明,该系统可用于电子健康、人机交互、高精度室内目标跟踪等多种应用场景。
