What is millimeter wave radar? What is the technology application principle of millimeter wave radar? What are the differences and advantages of millimeter wave radar compared with traditional radar technology? Millimeter wave radar technology is widely used in the field of automatic driving. Compared with the application of indoor scenarios, it has a big difference in technology licensing and working principle. Cars are motion vehicles measuring relative motion, indoor applications are static measurement of fretting. This is a big challenge for people in the industry. From the technical point of view, millimeter wave radar technology has the advantages of small size, light weight, narrow beam, high precision, strong anti-interference ability and so on. In the application side, millimeter wave radar technology supports all-weather tracking and high resolution multi-target monitoring.
The common human body sensor in the market, namely PIR passive pyroelectric infrared sensor, has a history of several decades, but it always has a problem: it can only do motion detection, can not make accurate judgment. Human bodies were installed in restrooms and meeting rooms, and lights were mistakenly turned off if people's movements were not detected. Currently, many smart cameras also have motion detection and humanoid recognition, but these vision-based products pose privacy concerns.
At the end of the product, there is a millimeter wave radar module on the human body and a sensor on the human body, which can monitor the static human body through the millimeter wave radar and accurately judge whether there is a human being. It can detect spatial positioning, approach distance, etc. The monitoring range covers 120 horizontal angles, and the radial detection is 10 meters, which supports the intelligent linkage of the whole house. At the same time, compared to tradition, compared to tradition. The application of PIR technology, the application of millimeter wave radar technology is stable and unconditional, in addition to improving the living experience of the bathroom and living room, but also make the office and home scene more energy saving; Millimeter wave's low privacy leakage can also make users feel at ease. The deep application of the millimeter wave radar module in the smart home scenario will also greatly stimulate the connection and integration between people, devices and Spaces, and greatly help the connection between multiple devices, connections and stability.
Single product, a variety of ceiling and wall mount, presence, vital signs, fall monitoring applications. The human body has a millimeter wave radar module sensor, which supports static detection, indoor positioning, and interference source configuration. Cloud support for presence, indoor location and fall recognition. Regarding the application of millimeter wave spatial positioning, the application data of the new generation of human body sensors accounts for one third of the spatial positioning scenarios. This is a highly sought after skill. Many geeky gamers praise the interior for its GameChanger feature positioned throughout the house.
Spatial positioning is a huge innovation for smart homes what mobile phones are for the Internet. Compared with the desktop, mobile Internet era of the desktop era. PC In the Internet era, the number of mobile applications has exploded greatly, the interaction frequency between applications and users has been greatly improved, and the response speed and experience of scenes have also been greatly improved. The scene first serves people. In the intelligent field of the whole house, people, equipment and space need to be connected. In the past, the connection was defective and ordinary human body could not be connected. The human body has the positioning function of millimeter wave radar module, which makes the connection of each end become a reality. In the future, with the help of indoor positioning, the whole house scene can realize seamless connection. From the development of the millimeter-wave radar technology industry chain, the current millimeter-wave radar technology is mainly used in intelligence, health monitoring, household appliances three fields, based on chip, module and other technologies to bring new improvements and changes to equipment products.
What is the development stage of millimeter wave radar technology? Compared with the traditional radar technology, the application of millimeter wave radar technology is relatively late. Millimeter wave radar technology was applied only sporadically in automobiles and other fields in the early 2000s, while its widespread application in China was relatively late, but it developed faster. Since 2015, many Chinese manufacturers have started to dabble in different band areas such as millimeter wave radar, and have achieved outstanding results in different segmented applications such as health management and monitoring.
In view of the future technological development direction of millimeter wave radar, from the perspective of intelligent users in the whole house, the millimeter wave radar module in the human body has the following application path, and the technological development of millimeter wave in this field will also match accordingly. Does anyone need to implement static presence detection and conventional CFAR? This method cannot completely cover all the millimeter wave presence judgment, interference recognition, spatial background adaptive, software compensation methods, and even with the active application of multipath effect, help visual distance presence judgment; Where the people are, how many there are. It is necessary to use millimeter wave Angle recognition, distance recognition, multi-target tracking, and ghost elimination algorithm according to the negative features of multi-path effect. How people are, what state.
In the current scheme design of smart home system, the application advantage of the MMW radar module functional products is gradually prominent. MMW radar functional products can bring more accurate judgment, realize more accurate linkage, and greatly improve the accuracy and stability of the products. In the basic scenes such as human start-up, etc. At the same time, millimeter wave radar can also greatly improve the accuracy of monitoring sleep, breathing, elderly fall posture judgment and other complex scenes.
At the same time, as for whether the millimeter wave radar technology that the industry is more concerned about will cause certain harm to the human body, iphone12 and iphone13 in the United States support the millimeter wave frequency band. The impact of millimeter wave radar module on human body is far lower than that of ordinary smart phones, which can be negligible. There is no need to worry too much.
At the same time, in view of the difference between millimeter wave radar sensor and microwave sensor, millimeter wave is actually only a part of microwave, and the technical performance wavelength is short, and the detection ability is small. In addition, compared with traditional infrared sensors, millimeter wave radar sensors have higher accuracy in motion detection and can determine the direction, speed, distance and position of moving objects. With the reduction of costs and the development of algorithms, replacing PIR technology with radar technology has become a new trend. In addition, in the same scenario application, after secondary calculation and related product position adjustment and avoidance, many millimeter wave radar sensors will not affect each other when working at the same time. In terms of cost control, although there is a big difference in the price of domestic millimeter wave radar sensor products, with the development of technology, the advantage of millimeter wave radar sensor products in cost control will be further prominent.
In future applications, the millimeter wave radar module of human body will be able to apply AI technology to achieve better integration, and bring more efficient functional processing at the application side and management side. In the future scenario application, millimeter wave radar technology will have a wide range of applications in household appliances, health care, whole-house intelligence and other fields.
