The spectrum of scattered radar signals from complex ground targets

This paper records the spectrum of some types of radar pulses scattered by complex ground based targets. A frequency-domain full wave Electromagnetic (EM) model of targets reveals significant distortion of the spectrum of the scattered signal in relation to that of the incident signal in many cases. Scattering is examined in monostatic cases only. The results lead into a deeper understanding of the scattering mechanisms and the quantification of echoes of complex ground targets. This can lead one to categorise ground targets differently from other features such as surface clutter and target shadows.
