Wind speed estimation of low-altitude wind-shear based on multiple Doppler channels joint adaptive processing

Abstract

When the airborne weather radar detects low-altitude wind-shear field, the echoes of wind-shear field are usually covered by strong clutter. In this paper, a novel method of wind speed estimation of low-altitude wind-shear based on multiple Doppler channels joint adaptive processing approach is proposed. The method constructs reduced-rank adaptive processors aimed to distributed meteorologic target to achieve clutter suppression and signal matching, and to obtain the wind speed of the wind-shear field. The experimental results show the proposed method can achieve clutter suppression and get accurate wind speed estimation with low computational burden.
