Agile multiple-pulse coherent lidar for range and micro-Do

摘要

Abstract: A novel high time-bandwidth product waveform lidar has been developed. The lidar operates at the eyesafe 2 $mu@m wavelength and produces a sequence of two or more cavity- dumped pulselets with a controllable intra-pulse spacing. The number of and spacing for the individual pulselets is adjusted to match the target and atmospheric characteristics. This waveform agility enables the sensor to operate at very long stand-off ranges. Performance predictions and results from recent field demonstrations are described.!0
