Radar cross section of some simple and collected targets to be used for classification

The goal of this paper is to analyze the scattering properties of different kind of targets, from simple shapes to collected targets made up of several objects, from 400 MHz to 7400 MHz to be used as patterns in a Ground Penetrating Radar in the classification stage. The data have been collected in an anechoic chamber with a vector network analyzer (VNA) set to work as a Stepped Frequency Continuous Wave Radar (SFCW). The data are analyzed in frequency and time domain in order to picture the radar cross section dependency of frequency, incident angle, polarization and target's shape. The measurement have been carried out using a bistatic arrangement with two TEM horns for linear polarization and two spiral antennas for circular polarization.
