摘　　要：连续波体制雷达的发射功率可在一段时间内实现功率平均分配,发射峰值功率小、环境适应性强,因此易于结构优化、电路简单。文章在STM32架构上设计了一款24GHz毫米波调频连续波(frequency modulation continuous wave,FMCW)雷达系统。经LabView平台仿真和实物验证,最终可生成频率为100Hz,峰值为2.56V的调频连续波。该系统由于易实现、效率高,可在自适应巡航和交通监管等方向开展应用。The transmission power of the continuous wave radar can realize the average power distribution within a period of time,the transmission peak power is small,and the environmental adaptability is strong,so it is easy to optimize the structure and the circuit is simple.This paper designs a 24 GHz millimeter wave frequency modulation continuous wave(FMCW)radar system on the STM32 architecture.Through LabView platform simulation and physical verification,it can finally generate a frequency-modulated continuous wave with a frequency of 100 Hz and a peak-to-peak value of 2.56 V.Due to its easy implementation and high efficiency,this system can be applied in adaptive cruise and traffic supervision.
