Abstract

Abstract

In order to solve the problem of inaccurate estimation of low-altitude wind-shear wind speed under non-uniform clutter environment, a kind of low-altitude wind-shear wind speed estimation method based on echo power screening and Digital Land Classification Data (DLCD)-assisted is proposed. The method firstly uses the sample echo power to select initially the training samples, then uses the DLCD to calculate the similarity between the samples, and selects the training samples with higher sample similarity from the higher-powered training samples to estimate the clutter covariance matrix, finally uses the Generalized adjacent Multiple-Beam (GMB)-Joint Domain Localized (JDL) method to achieve wind speed effective estimation of low-altitude wind-shear.
