What is millimeter wave radar technology? What is the application principle of millimeter wave radar technology? As the name suggests, millimeter wave radar module technology is a radar operating in the millimeter wave frequency band. Millimeter wave is located in the wavelength range where microwave and far infrared wave overlap, so millimeter wave has the advantages and unique properties of these two spectrum. The theory and technology of millimeter wave are the extension of microwave to high frequency and the development of light wave to low frequency. At the same time, MMW radar transmits a linear frequency modulation pulse signal, which is reflected back after encountering the target. The target distance can be calculated by analyzing the delay of the echo signal, which is one of the basic application principles of millimeter wave radar technology. In addition, from the technical point of view, millimeter wave radar technology has the advantages of small size, light weight, narrow beam, high accuracy, strong anti-interference ability and so on.

In applications in the smart home scenario, MMW radar module technology will also greatly stimulate the connection and integration between people, devices and Spaces, greatly assisting the connection, communication and reliability between multiple devices. Regarding the ranging accuracy of millimeter wave radar technology in specific applications, Mr. Li Guohao said that the accurate detection range of millimeter wave radar products is about 10 to 20 meters, including whether there are people and static. Based on the accuracy of millimeter wave radar technology in ranging and speed measurement, it has been widely used in intelligent transportation, parking management and other fields.

In conclusion, millimeter wave radar technology has strong scene adaptability. In dark and complex environments such as haze on rainy days, millimeter wave radar can still operate correctly, and it is more reliable and cost-effective than other technologies. In recent years, the application of smart home has become a new scene of millimeter wave radar module technology. What is the structure of the industrial chain from chip to product? Millimeter wave industry chain includes chip end, module end, product end and platform end. From a product-side perspective, many traditional and smart home appliance manufacturers have licensed relevant millimeter wave radar technology into their products to enhance their intelligent capabilities. At the same time, as the future technology continues to mature, the MMW radar module will be upgraded iterably, the range of applicable scenarios and the depth of application will be significantly improved, and become an important technical component of the smart home industry.

Is millimeter wave radar technology capable of penetrating walls and obstacles in specific scenarios? Can millimeter wave Radar identify animals accurately? Millimeter wave radar technology generally cannot penetrate walls and glass, but can penetrate thin wood and plastic. When the bathroom scene needs to find the human body through glass and other partitions, the human body target can be found through multipath reflection; In situations where penetration is not required, such as a small conference room, shielded areas can be set up to shield targets outside the wall. Compared with the conventional antenna radar, the antenna of multi-antenna array is more accurate in distinguishing human from animal.

In the face of the new technology application of millimeter wave radar, how to define the product boundary from chip to product? The application of millimeter wave radar technology is a very deep industry chain, which requires close contact and communication from upstream to downstream. Human or unmanned judgment is a technical difficulty in the concrete application of millimeter wave radar module technology, which will be subject to more interference factors and requires more accurate identification logic. In this process, a number of techniques are applied to ensure and upgrade the relevant capabilities, including spatial adaptive strategy, target tracking, clutter suppression, etc. The application principle of millimeter wave radar technology in motion, space, direction, near and far detection is not complicated, which reflects the continuous working ability and more accurate judgment ability of the technology. At the same time, MMW radar module products also have more targeted and accurate linkage ability in specific scenarios. Millimeter wave radar can also greatly improve its accuracy in the monitoring of sleep, respiratory heart rate abnormalities, elderly fall posture judgment and other complex scenes. In the future, local and cloud data analysis and anti-jamming capabilities need to be improved in the process of promoting millimeter-wave radar technology productization.

In the future, the human body sensor based on millimeter wave radar technology will become the focus of the industry. Millimeter wave radar module technology has a wide range of application depth and exploration direction in hardware and software, including chip, antenna design capability, software algorithm, application scenario, business model and other innovation opportunities. The product form expression will be more diversified, forming a rich product matrix. And combined with smart screen, home camera and other hardware products to expand its application range. From an industry-wide perspective, millimeter wave radar technology is not a single technology component. Among the smart product components throughout the house, sensors based on millimeter-wave radar module technology can enable many product upgrades. Meanwhile, it can also improve its cloud management and data processing capabilities by deeply integrating with AI+IoT and other technologies, bringing new impetus to product innovation.
