摘　　要：为了提高无人机飞行安全,文章提出了一种77G线性调频连续波防撞雷达设计方案。系统基于IWR1642毫米波雷达传感器构建,利用内部集成的ADC,DSP和ARM实现数据采集、信号处理、系统控制和通信功能,实现了对无人机飞行前向障碍的检测及障碍物距离、速度和角度等信息的提取,有效解决了已有防撞雷达系统的成本高、功耗高和体积大等问题,方便小型无人机平台搭载。实验结果表明该系统运行稳定,满足设计指标。In order to ensure the flight safety of UAV, this paper proposes a design of 77 G linear frequency modulation continuous wave anti-collision radar. The radar system based on IWR1642, built based on a single-chip millimeter wave sensor, takes advantages of ADC, DSP and ARM to realize the data acquisition, signal processing, system controlling and communication functions, and the detection of UAV forward obstacle and the extraction of obstacle distance, speed and angle are realized, which effectively overcomes the problems in hardware cost, power consumption and size of existing anti-collision radar systems and it is easy for small-scale drone platforms to carry. The test results show that the system is stable and meet the criteria of design.
