摘　　要：为了解决多普勒信号由于受到周围环境影响而难以分析出其信号频率的问题,结合LabVIEW和MATLAB各自的优点,采用NI(National Instruments)公司的USB-6215数据采集卡和Burg谱估计算法在简易速度测试装置中进行混合编程。大量的测试结果证明了该方法的可行性。Because Doppler signal is vulnerable to impact of the surrounding environment,its frequency is difficult to analyze with general digital signal processing methods.The mixed programming of Burg spectral estimation algorithm was carried out with LabVIEW and MATLAB,and a simple speed testing system which consists of Doppler speed sensor,USB-6215 DAQ（Data-Acquisition） made by National Instruments and PC was experimented.The experimental results showed that the system is feasibility and accuracy.
