Design of a near range moving object detection system based on microwave radar

Abstract： In order to quickly identify moving objects within a certain range and improve the accuracy of detection, a close-range moving objects detection system based on STM32 and microwave radar is designed. The system uses the Doppler principle of electromagnetic waves to detect differences in the wavelength of reflected waves from moving objects. The received signals are processed through STM32 and optimization algorithms to improve the speed and accuracy of detection. Finally, the system test shows that the system has the ability of low cost, stable working environment, fast and accurate display.
