摘　　要：设计了基于激光二极管自混合效应的速度传感器,提出了基于线性预测二阶自回归光谱计算的信号处理方法,并对该速度传感器在干燥、洁净的路面进行了测试,其标准偏差为σ≈0.22%.实验结果表明,该传感器是有效的.The velocity sensor based on the self-mixing effect of the laser diode was described. The signal processing method based on a second-order autoregressive-spectral estimation method was presented. The sensor was tested on a dry and clean road with a standard deviation of 0.22 %. The experimental results show the sensor is effective in velocity measurement,
