Spectral analysis based on the linear dynamic model

PDFRead

Abstract. The paper considers some problems (tasks) in the framework of dynamic simulation including inverse and ill-posed tasks. It has been established that the classical solution of these tasks can be found in the context of so-called amplitude methods which resolution capability is in principle restricted by a length of a direct impulse wave. The reasons of weak resolution capability of amplitude methods have been analysed. Some proposals allowing to increase 1-2 orders of resolution capability of methods of some ill-posed tasks' solution have been made.

Keywords: linear model, spectrum, high resolution, analytic representation of spectrum, autocorrelation function
