What are the mainstream radars used for human body detection?
The mainstream radars used for human body detection mainly include the following types: Millimeter-wave radar , LiDAR, and ultra-wideband radar.
First is millimeter-wave radar, which uses electromagnetic waves in the millimeter‑wave band for detection. It features strong penetration, high resolution, and robust anti‑interference capabilities. In human‑body sensing, millimeter‑wave radar can accurately capture subtle body movements and is widely employed in security surveillance, smart homes, and autonomous driving, among other applications.
Next is LiDAR, which detects the distance, velocity, and position of target objects by emitting laser beams and receiving the reflected signals. LiDAR excels in human‑body detection, with its high precision and high resolution enabling it to accurately identify human silhouettes and movements even in complex environments. Consequently, LiDAR is widely employed in applications such as robot navigation, human tracking, and 3D body scanning.
In addition, there is ultra-wideband radar, which employs ultra-wideband signals for detection and offers advantages such as strong anti‑interference capability, excellent penetration, and high positioning accuracy. In human‑body sensing, ultra‑wideband radar can penetrate walls, obstacles, and other obstructions, enabling precise localization of individuals. This makes it highly valuable in applications like emergency rescue, medical monitoring, and prison surveillance.
In recent years, with the continuous advancement of artificial intelligence technologies, radar-based human detection techniques leveraging deep learning have also made significant progress. By training deep-learning models, these systems enable radars to more accurately recognize human body characteristics and behavioral patterns. Looking ahead, as the technology continues to evolve and its application domains expand, deep-learning–driven radar-based human detection is poised to become one of the mainstream methods for human detection.
In summary, there is a wide variety of mainstream radar technologies for human detection, each with its own unique characteristics. In practical applications, it is essential to select the appropriate radar type based on the specific scenario and requirements to achieve optimal human‑detection performance.
