【摘要】 激光测速在工业生产中有着广泛的应用前景。介绍了一种基于半导体激光器的激光测速系统,在该系统中采用了与传统的测速系统不同的专用数值处理算法和弱信号提取技术,从而克服了在强噪声背景下的提取弱信号Doppler频率的困难,提高了测速精度,仿真结果也证实了这一点。更多还原

【Abstract】 Laser detect velocity system will be used abroad in industry application. a high quality laser detect velocity system is introduced, in which the special digital arithmetic and weak signal abstraction technology have been used. The proposed methods overcome the shortcoming of abstraction of the weak signal ,and improve precision of its detect velocity,which has been proved by simulation.更多还原
