Abstract: In response to the current demand of market for indoor personnel dynamic detection, a 60 GHz millimeter-wave radar-based human sensory detection system is designed. The system uses IWR6843 as a processor for data signal processing and algorithm implementation, and PMICLP87524 as a multi-channel programmable The high-precision power supply system, combined with the on-board three-transmit and four-receive antenna design, uses a high-frequency 6-layer PCB to realize the design plan, which can accurately detect the distance, angle, speed, acceleration and other information of indoor activities. The system does not involve privacy issues, is not affected by light, has fast response speed, high positioning accuracy, and wide detection range. The test proves that the horizontal detection range of the system can reach ±75°, the upper and lower detection range is ±40°, the detection distance can reach 8 m, the distance output accuracy can reach 0.1 m, the angle output accuracy can reach 1°, and the comprehensive detection of some scenes is accurate The rate can reach more than 90%.
