基于DSP的防撞雷达信号采样系统设计

摘要

Directed toward the linear frequency modulation continuous wave radar, an ADC which has two simultaneous differential inputs is chosen, and a system based on SPORT port of DSP is designed to sample the I and Q quadrature signals. Tlie system validity is validated via experiments.%针对线性调频连续波汽车防撞雷达回波信号的特点,选用串行差分ADC,设计了一种基于DSP的SPORT口的I、Q双通道采样系统,并通过实验验证了系统的正确性.
