A. V. Nemov, D. Yu. Tyuftyakov · 2021
The subject of the paper is a description of some features of antijamming algorithms functioning, based on the principal components method in correlation analysis under a priori uncertainty regarding the number of jammers. Algorithms can be applied to GNSS. This paper presents the results of the analysis of power characteristics of algorithms for spatial signal processing, including on-the-fly estimation of a signal subspace dimensionality of a covariance matrix using eigendecomposition and information criteria.
