Methods and equipment for determining one or more attributes of at least one target based on spatial-oriented analysis of radar signals

Abstract

The invention relates to methods, systems, computer-readable devices and equipment for determining one or more attributes of at least one target based on the spatial analysis of radar signals. In some cases, the subset of eigenvectors used to create the spatial signal or multiple is determined based on principal component analysis. In some approaches, the subset of eigenvectors is determined by estimating the total number of data points using the discrete Fourier transform (DFT) or other spectral analysis techniques. In other approaches, the DFT is used to identify regions of interest for performing eigenspace analysis. According to some approaches, DPT is used to estimate one attribute of the target and eigenspace analysis is performed to estimate another attribute of the target, with the results combined to create a multidimensional representation of the observational range.
