A lidar technique employing temporally stretched, frequency chirped pulses from a 20 MHz mode locked laser is presented. Sub-millimeter resolution at a target range of 10.1 km (in fiber) is observed. A pulse tagging scheme based on phase modulation is demonstrated for range resolved measurements. A carrier to noise ratio of 30 dB is observed at an unambiguous target distance of 30 meters in fiber.
本文介绍了一种激光雷达技术，该技术采用来自20MHz锁模激光器的时间拉伸、频率啁啾脉冲。在10.1公里（光纤中）的目标距离处观察到亚毫米分辨率。演示了一种基于相位调制的脉冲标记方案用于距离分辨测量。在光纤中30米的明确目标距离处观察到30dB的载噪比。
