[Guide] The 77GHz millimeter wave radar scheme can be made smaller than the 24GHz radar scheme. It has become the mainstream choice for automotive forward detection radar and has gradually penetrated into the industrial and infrastructure application market. The current mainstream suppliers are TI and NXP. But TI has made the industry's highest sensing accuracy and the smallest size of the 77GHz millimeter wave sensor portfolio. Today's world is rapidly changing to intelligence, and driverless cars have begun to run on the road. By 2020, there will be 10 million self-driving cars on the road. These smart cars must have the ability to automatically detect obstacles in front of the distance and accurately detect small objects in the tail without blind spots. Moreover, not only in the automotive sector, 81% of homes and buildings will be smarter by 2020, and smart streetlights and smart factory markets are also emerging. These application markets must be built on precise sensing technology. Jiang Hong, Director of Embedded Products Systems and Applications, TI Semiconductor Division, said: "The demand for sensing solutions is increasing, whether it is smart cars or smart street lights or security infrastructure applications, including: accurate detection of object distances , angle and speed, free from environmental conditions such as rain, fog, dust, light and darkness, can penetrate plastic, dry walls and glass. Millimeter wave is the only sensing technology that can meet all these needs. It can reach about 1 cm, and the sensing distance can be as far as 300 meters, which is beyond the reach of ultrasonic technology." The millimeter-wave solutions currently on the market are dominated by multi-chips, including transmitters, receivers, amplifiers, ADCs/DACs, and processors. Jiang Hong said: "The multi-chip millimeter-wave radar solution has many shortcomings, such as large power consumption, large size, complex design, and long time to market. Recently, TI's new millimeter-wave single-chip CMOS product portfolio includes five solutions. Across the two product families of 76 to 81 GHz sensors with a complete end-to-end development platform, the AWR1x and IWR1x sensor portfolio offers up to three times the sensing accuracy and the smallest package size compared to current millimeter-wave solutions on the market. Only 10 mm square, the sample is available now." TI AWR series of millimeter wave sensors are mainly for the automotive market. There are three products: AWR1243, AWR1443, and AWR1642. The IWR series is mainly for the industrial market. There are 2 products, IWR1443 and IWR1642. The AWR1243 only integrates RF RF and is mainly used to implement medium and long-range radar. Applications include: emergency braking of vehicles, adaptive cruise control and automatic altitude driving. The AWR1443 integrates RF and MCUs for primary proximity sensing, including occupant detection, body sensors, in-cab gesture recognition, and driver monitoring. The AWR1642 integrates RF, MCU and DSP, and is mainly used to implement ultra-short and short-range precision radar. Applications include: blind spot detection, anti-back collision/warning, lane change assistance, pedestrian/bicycle detection, anti-collision, intersection traffic alarm, 360 Degree of view, parking assistance. Industrial millimeter wave sensors IWR1443 and IWR1642 are mainly used for traffic monitoring, perimeter safety, intelligent street lights, liquid level detection, forklifts, drones, robots, and personnel counting. Highly integrated: With a fully integrated CMOS single-chip (integrating the best digital signal processor (DSP) and microcontroller (MCU) in its class or with only one MCU or DSP), designers can choose the best processing for their needs ability. Each chip provides intelligent, high-precision independent sensing with a range resolution of less than 4 cm, distance accuracy as low as less than 50 microns, and a range of up to 300 meters. Comprehensive product lineup: A portfolio of five devices allows designers to choose the right solution for their design needs while reducing power and board space by 50%. Highly intelligent: TI's millimeter-wave 76-to-81GHz single-chip sensor portfolio dynamically adapts to changing conditions and conditions, supports multiple functional modes to avoid false alarms, and provides a wide range of sensing for a wide range of applications. Environmental Flexibility: The IWR1x and AWR1x millimeter wave sensors can be used to sense plastic, dry walls, clothing, glass and many other materials, and can be exposed to environmental conditions such as light, rain, dust, fog or frost. Get started today: TI's new millimeter-wave software development kit (SDK) includes sample algorithms and software libraries that simplify RF design with less than 20 simple application programming interfaces (APIs). By leveraging TI's mmWave SDK platform, engineers can start their application design work in less than 30 minutes. Often, developers encounter obstacles when creating a Society of Automotive Engineers (SAE) International Level 2 and above in a vehicle, primarily from sensor size and powering specific components. With built-in quality standards, unprecedented precision in small form factor and low power packages, TI's AWR1x millimeter wave portfolio enables developers to meet these requirements while achieving low cost. Designers can not only improve the safety features of Advanced Driver Assistance Systems (ADAS) and autonomous driving – including ISO 26262 for Automotive Safety Integrity Level (ASIL-B) – and provide automatic parking assistance, pedestrian detection, and bearer New features such as rate and driver monitoring. To address the need for greater efficiency in factories, building automation systems, and smart infrastructure, developers can now take advantage of TI's intelligent and robust millimeter-wave sensor portfolio. In addition, this sensing technology can be used to retrofit existing functions in demanding applications such as medical equipment, tank level sensing, robot vision and drones. TI's IWR1x millimeter-wave non-contact sensors are immune to ambient light, rain, dust, fog or frost, making them robust indoors or outdoors. By determining the extent, velocity and angle of the objects around the device, these sensors can immediately adapt to dynamically changing scenes. Texas Instruments is introducing unprecedented precision and intelligence into a wide range of applications, including automotive, factory and building automation, and medical markets. The combination of precision analog design technology and digital signal processing enables designers to implement intelligent and contactless sensing in their systems.
