Portable Pulsed Coherent Lidar for Noncooperation Targets at the Few-Photon Level
The decoherence in coherent lidar becomes serious with the increase in distance. A small laser spot can suppress the decoherence of the echo light from noncooperation targets. However, it is very difficult to keep a small light spot over a long distance. In this paper, a pulsed coherent lidar with h...
