The millimeter wave radar target recognition module is innovative in the detection of vital signs in the car cabin, and the millimeter wave radar has a keen "insight" ability for the slight movement of objects. This enables millimeter wave radar to accurately detect subtle vital signs such as respiration and movement, and to detect and measure information such as respiration rate and heart rate without contact. Human breathing can cause chest and abdomen fretting. The millimeter wave radar target recognition module can measure respiratory frequency by sensing fretting.
Achieve the core functions:
Mmwave radar target identification module integrates radar Baseband processing module (Baseband). In respiratory related applications, users can use the built-in baseband processing engine to configure registers to complete the preprocessing of respiratory heartbeat signals. The integrated 300MHz main frequency 32-bit microprocessor, 640-bit KB memory space and 1MB expandable memory space, meet the user's needs for further personalized algorithm processing.
Typical breathing process of millimeter wave radar target recognition module:
Among them, the selectable distance compression and respiratory heartbeat signs point baseband processing module can be completed in real time and efficiently. An ARC implementation processor that integrates phase extraction, spectrum analysis and respiration estimation can be used. At the same time, the user can further use the Doppler FFT and DoA in the signal processing baseband to realize the separation of environment and static, moving target perception, direction finding and other functions.
Application scenario of millimeter wave radar target recognition module:
Based on the core function of breath detection, millimeter wave radar can be applied to various application scenarios such as intelligent cockpit. With the development of automobile industry, cockpit has gradually become the "third space" of people's work and life. It is the development trend of intelligent cockpit to improve safety and comfort and improve driving experience. In real life, car owners often use children or pets for long periods of time. "Forgetting" in the cockpit, in a hot environment, this behavior can lead to very serious consequences.
The cabin life detection scheme based on the target recognition module of millimeter wave radar can solve the problem of "worry at home". The cockpit life detection plan adopts the dual strategy of sensing moving target and micro-moving target to comprehensively determine whether the personnel exist. Judging whether there is human activity by non-zero Doppler; When there is no moving target, the presence of vital signs is judged by breathing and heart rate detection. At the same time, by monitoring the driver's breathing and other physical signs, the driver's physical condition can be monitored and the potential dangerous state can be warned in time.
Whether there is living body detection vital signs information monitoring:
Breath testing will also be widely used in smart homes, pensions, healthcare and other fields. The MMwave radar module is installed in smart mattresses, elderly monitoring beds, cribs and other products, which can measure and collect characteristic data such as respiration and heartbeat in real time, and transmit the data to the background system in real time to play the role of prompting and monitoring.
Millimeter wave radar target recognition module solution:
Millimeter wave radar has SDK complete software and hardware solutions, users can quickly realize the development of radar sensors. The advantages of miniaturization and easy development can help customers quickly complete product design, reduce R&D investment, and more easily be widely used in automotive, medical and other fields, to provide safer and smarter sensing solutions for society.
