Calculation of the spectral density of the signal using a variable configuration antenna array
V. M. Zhuravlev, S. V. Fundaev Ulyanovsk State University, Ulyanovsk
Abstract:
The problem of calculation of spectral density of wave process are represented in this work on base of data from antenna array with variable configuration. This antenna array is an aggregate sensing elements moving in space with constant velocities related to laboratory frame system and related one another. The new way of transformation an initial data set obviated difficulties with inhomogeneous Dopler's shifts in antenna nodes are suggested. The some realization of such method for a discreet time series are represented.
Keywords:
multidimensional spectral analysis of signals, spatial-temporary spectra, antenna array with variable configuration, the method of normal principal components, an estimation of spectral densities.
