Investigation of ambiguity function of ultra-wideband radiometric complexes with multi-antenna system

Abstract

Analytical expression for the ambiguity function ultra-wideband radiometric complexes with multi-antenna system is derived. The dependencies of ambiguity function on geometric position and quantity of antennas and using input tracts (narrow-band, multi-band, ultra-wideband) are investigated. It is indicated that using multi-antenna systems with the ultra-wideband and multi-band signal processing allows to form ambiguity function with one main lobe.
