Millimeter-wave (mmWave) radar, as an emerging technique, is increasing in popularity for human activity recognition. In contrast to traditional sensors and radars, mmWave radars give detailed information on objects from the range domain to the Doppler domain. The short wavelength allows mmWave radars to achieve a high resolution and a small antenna size, but also makes them prone to noise. In this article, we present a system framework for human detection and tracking using mmWave radars. We show that mmWave radars have good performance in indoor environments, with over 90% sensitivity. We show that using a single radar can raise a large number of false alarms due to unstable data and noise. However, with two radars the precision of the system can be improved significantly.

使用毫米波雷达进行高精度人体检测和跟踪

毫米波 (mmWave) 雷达作为一种新兴技术，在人类活动识别方面越来越受欢迎。与传统传感器和雷达相比，毫米波雷达提供从距离域到多普勒域的对象的详细信息。短波长使毫米波雷达能够实现高分辨率和小天线尺寸，但也容易产生噪声。在本文中，我们提出了一个使用毫米波雷达进行人体检测和跟踪的系统框架。我们表明毫米波雷达在室内环境中具有良好的性能，灵敏度超过 90%。我们表明，由于数据不稳定和噪声，使用单个雷达会引发大量误报。但是，使用两个雷达可以显着提高系统的精度。
