The boundary layer wind profile radar is a high-performance clear sky atmospheric detection and remote sensing device that uses solid-state active phased array technology to continuously provide real-time distribution of meteorological elements such as horizontal wind field, vertical airflow, atmospheric virtual temperature, and atmospheric refractive index structure constant (Cn2) from the ground to the upper atmosphere with altitude. The instrument is mainly used for observing the atmospheric wind field in the low troposphere, monitoring the diffusion process of local environmental gas pollution such as sandstorms, and monitoring and forecasting of small-scale catastrophic weather; As an effective tool for airport airspace airflow monitoring, it can provide high-density detection data for airport flight meteorological support, and is an important meteorological support service tool for various scientific experiments, test sites, and large-scale events.
