基于 STM32 单片机的 模拟雷达探测设计系统 Design of simulation radar detection system based on STM32 中文摘要通过长期的社会观察以及网上数据调研发现，雷达的应用十分广泛。但普遍的雷达设备体积大，不利于携带。而民用的常用小型雷达如：车载雷达、扫地机器人等，存在精确度不高、功能单一等缺点。故本系统针对这一现状设计出一种精确度高、小型易携带、能显示障碍物的雷达探测设备。本设备采用 STM32F103C8T6 作为主控制核心板，选择使用超声波信号作为主要探测信号，避免探测时对人体或物体造成伤害，具有成本低、速度快的特点。超声波信号发送出去后，通过计算模块记录数据并经过算法处理得出障碍物的方位以及距离，同时添加预警功能模块根据所得位置信息判断当前是否要发出报警信号，提高预测性和安全性。软件程序部分主要控制整个单片机进行信号发送、接收数据并处理数据能让数据正确显示在界面上。经过多次实验结果测试：在忽略温湿度和声波衰减影响下，本探测雷达设备在可测距范围内可实现准确的距离测量，实验结果最大的平均误差不高于 5%。在整个信息处理过程，数据都能够快速实时更新，实验结果能够达到预期效果。关键词：STM32 雷达扫描 超声波测距 距离报警 蓝牙通信Abstract Through long-term social observation and online data research, it is found that radar is widely used.But the general radar equipment is bulky and not suitable for carrying.But the civil commonly used small radar such as: car radar, sweeping robot, etc., there are not high accuracy, single function and other shortcomings.Therefore, this system designs a kind of radar detection equipment with high accuracy, small and easy to carry, and can show obstacles.This device adopts STM32F103C8T6 as the main control core board, and selects ultrasonic signal as the main detection signal to avoid causing harm to human body or object during detection.Low cost investment and fast propagation speed are the advantages of ultrasound.After the ultrasonic signal is sent out, the location and distance of the obstacle can be obtained by re...
