基于STM32单片机的模拟雷达探测设计系统

AbstractThrough long-term social observation and online data research,it isfound that radar is widely used.But the general radar equipment is bulky andnot suitable for carrying.But the civil commonly used small radar such as:car radar,sweeping robot,etc.,there are not high accuracy,single functionand other shortcomings.Therefore,this system designs a kind of radardetection equipment with high accuracy,small and easy to carry,and canshow obstacles.This device adopts STM32F103C8T6 as the main controlcore board,and selects ultrasonic signal as the main detection signal to avoidcausing harm to human body or object during detection.Low cost investmentand fast propagation speed are the advantages of ultrasound.After theultrasonic signal is sent out,the location and distance of the obstacle can beobtained by recording the data of the calculation module and processing thealgorithm.Meanwhile,the warning function module can be added to judgewhether to send an alarm signal according to the obtained locationinformation,so as to improve the predictability and safety.The softwareprogram mainly controls the whole SCM to send signals,receive data andprocess data so that the data can be displayed correctly on the interface.Byanalyzing the results of multiple test data,it is found that the detection radarsystem can achieve accurate range measurement within the rangemeasurement range without the influence of temperature,humidity and
