摘要
研究了一种基于多普勒效应测速的光频率调制连续波相干激光雷达测速方案。该方案采用全光纤结构，效率高、体积小、功耗低、性能稳定可靠，具有良好的机动平台挂载适应能力。对雷达原理、结构、数据处理算法等部分进行了详细讨论。另外，还给出了直升机飞行挂飞实验结果：最大测量速度为150 m/s,作用距离大于3 km，最大测量误差为0.08 m/s。
Abstract
An optical frequency modulated continuous wave coherent lidar technology for velocity measurement based on the Doppler effect is presented. The technology uses all-fiber structure. It has advantages of high efficiency, low power consumption, stable and reliable performance, with good ability to adapt to a mobile platform. Radar principles, structures, data processing algorithms and other related parts are discussed in detail. Flying helicopter hanging results are also given: the maximum measurement velocity is 150 m/s, the measuring range is over 3 km, and the maximum measurement error is 0.08 m/s.
