Abstract

An ultrawideband random noise radar operating in the 1 - 2 GHz frequency range has been developed at the University of Nebraska-Lincoln. A unique signal processing procedure is utilized that preserves the phase of a received signal thus making it possible to use this radar as a coherent receiver. This allows the UWB random noise radar to be configured as an inverse synthetic aperture radar. Turntable experiments are presented here. HH, HV, VH, and VV data is taken giving fully polarimetric images. Image formation is performed with a short-time Fourier transform as well as with the Wigner- Ville distribution.
