Spectral method for the spatio-spectral sensitivity domain filling in aperture synthesis system

Abstract

The methods of filling the domain of spatio-spectral sensitivity (SSS) are considered. The spectral method for filling the SSS domain in aperture synthesis systems is proposed. It is shown that instead of filling the SSS domain of the serial synthesis using one radio-interferometer with variable base expedient to use fixed antennas and ultra-wideband (UWB) signals processing. The criterion for the uniqueness of the main lobe of the ambiguity function of the two-antenna array using UWB signals processing is obtained.
