A New Radar Echo Generation Model for Ultra-Low Altitude Targets in Far-Field Conditions

open access: yesInternational Journal of Antennas and Propagation, 2022
This paper proposed a new radar echo simulation method for ultra-low altitude targets in far-field conditions. Based on the electromagnetic (EM) scattering calculation of target and environment, combined with the weighted four-path model, the scattering ...
