【摘要】 多普勒频率提取算法是激光多普勒测速雷达的关键技术之一,它会直接影响测速精度、作用距离、动态响应范围。本文以一款典型激光多普勒测速雷达为例介绍了测速系统的组成与关键技术,对比分析了国内外典型激光多普勒测速雷达的性能指标及技术参数,重点研究了各种多普勒频率提取算法,并对各种算法的优缺点进行概括总结。最后对多普勒频率提取算法进行了展望。

【Abstract】 Doppler frequency extraction algorithm is one of the key technologies of laser Doppler velocity radar. It has a direct effect on the measurement precision,operating range and dynamic response range. Taking a typical laser Doppler velocity radar as an example,the composition and key technologies of the laser Doppler velocity radar system are introduced. Performance indexes and technological parameters of typical laser Doppler velocity radar systems at home and abroad are compared and analyzed. Furthermore,varieties of algorithms which are used to extract Doppler frequency are studied. Also,the merit and demerit of these algorithms are summarized. Finally,the Doppler frequency extraction algorithms are prospected.
