Abstract

It is proposed and investigated a method for linear autoregressive models of radio-reflections optimization, based on procedure of autoregression vector coefficients weighting by modifying factor. It is shown, that proposed method allows computational shortcut for construction of overdetermined autoregressive models of radio-reflections up to 2–4 times by excluding multiplication procedure of rectangular correlation matrix of modeled process in overdeterminated linear equation systems.
