Design and Implementation of Radar Cross-Section Models on a Virtex-6 FPGA

Journal of Engineering, 2014
The simulation of radar cross-section (RCS) models in FPGA is illustrated. The models adopted are the Swerling ones. Radar cross-section (RCS) which is also termed as echo area gives the amount of scattered power from a target towards the radar.
