I. Introduction

With the continuous development of science and technology, sensor technology has penetrated into all aspects of our lives. Among them, millimeter wave radar sensor has attracted much attention in the application of human body detection due to its advantages of high precision, non-contact and real-time monitoring. This paper will introduce the application of millimeter wave radar sensor in human body detection in detail, including its working principle, advantages, and market status.

Second, the working principle of millimeter wave radar sensor

Millimeter wave radar sensor uses the characteristics of millimeter wave to detect human body without contact. Millimeter wave refers to electromagnetic waves with frequencies between 30 and 300 GHz, with wavelengths between 1 and 10 mm. Because the wavelength of millimeter wave is short, it has high penetration and diffraction, and can adapt to different environments.

Millimeter wave radar sensor sensing the human body sensor mainly uses the reflection and scattering principle of millimeter wave to irradiate the emitted millimeter wave to the surface of the human body, and calculates its propagation time and phase change by receiving the reflected and scattered millimeter wave, so as to obtain the position, speed, attitude and other information of the human body.

Third, the advantages of millimeter wave radar sensors

Non-contact detection: millimeter wave radar sensor Millimeter wave radar detection of human sensors Sensing human body sensors do not need to touch the human body, can detect the human body, to avoid the contact detection may bring cross-infection and other problems.

High precision: millimeter wave radar sensor has high detection accuracy, which can achieve accurate positioning and speed measurement of the human body.

Real-time monitoring: millimeter wave radar sensors can monitor information such as the position and speed of the human body in real time, which is suitable for scenarios that require real-time feedback.

Strong adaptability: The sensor of millimeter wave radar sensor sensing the human body has strong environmental adaptability and can detect the human body in different environments.

Fourth, the application of millimeter wave radar sensor in human body detection

Security monitoring: In important areas such as public places and banks, real-time monitoring of personnel can be carried out through millimeter wave radar sensors to prevent theft and other behaviors.

Five, millimeter wave radar detection of the human body sensor sensor in the application of smart home

With the popularity of smart homes, the application of millimeter wave radar sensors in family life is gradually increasing. For example, millimeter-wave radar sensors can be used in intelligent lighting systems to control the switching and brightness of lights through human sensing; In the intelligent air conditioning system, millimeter wave radar sensor can be used to detect the location and activity of indoor personnel, and realize the intelligent control and energy saving of air conditioning.

Six, the development trend of millimeter wave radar sensors

With the continuous progress of technology and the continuous growth of application demand, the development prospect of millimeter wave radar sensor sensing human body sensor is very broad. In the future, millimeter wave radar sensors will develop in the direction of smaller size, lower cost, higher performance and richer functions. At the same time, with the development of 5G, Internet of things and other technologies, millimeter wave radar sensors will be applied and promoted in more fields.
