Technical Analysis of Space-Based Coherent Wind LiDAR
Measurement of atmospheric wind field is very important for national safety, weather forecasting, aerospace and military applications. At present, our country is lacking of the comprehensive measurement capability of large-scale wind field. Light detection and ranging (LiDAR) is the sole instrument to access the three-dimension wind field profiler directly. The proposed space-based coherent Doppler wind LiDAR accesses the target Doppler frequency shift and calculates its line-of-sight velocity using laser heterodyne technology. Comparing with the traditional LiDAR, it has the prominent features of high space-time resolution and high sensitivity in dimension, especially in weight and power consumption. Illustrations focus on its principle and key technology. The intending space-based feasibility and prospect of the proposed coherent wind LiDAR are also given.
