Abstract
This paper presents a detailed case study on the application of 24GHz millimeter-wave (mmWave) technology for micro-motion sensing detection. Millimeter-wave sensing has gained significant attention due to its ability to detect subtle human movements with high precision, offering superior resolution compared to conventional RF-based sensing systems. The 24GHz frequency band, widely used in various industrial and consumer applications, provides a balance between signal range, resolution, and power consumption, making it suitable for micro-motion detection in smart environments.
The study investigates the performance of 24GHz mmWaves in detecting micro-motions such as hand gestures, breathing patterns, and small body movements in indoor environments. By leveraging the Doppler effect and variations in radio signal reflection, the system can accurately detect and classify human motion without requiring complex sensor installations. This paper discusses key challenges, including signal attenuation, environmental interference, and calibration issues. Solutions such as beamforming and multiple-input multiple-output (MIMO) techniques are proposed to mitigate these challenges, ensuring robust detection in real-world applications.
The experimental results demonstrate that 24GHz mmWave technology can achieve high detection accuracy and low latency, making it suitable for applications in healthcare, security, and smart homes. Additionally, this paper highlights the potential for integrating 24GHz mmWave sensors with IoT frameworks to enable real-time data processing and enhanced automation in smart environments. The findings underscore the feasibility of using 24GHz mmWave technology as a cost-effective and efficient solution for precise motion sensing in diverse applications.
