Radar penetration imaging using ultra-wideband (UWB) random noise waveforms

Ultra-wideband (UWB) radar has been proven to be a very powerful tool for high-resolution penetration imaging of obscured objects. The authors discuss a radar penetration imaging technique using UWB random noise waveforms. The theoretical foundations for random noise radar, the random noise radar imaging model, and the synthetic aperture radar (SAR) image formation algorithm are presented. Typical field test results using an experimental random noise radar system are demonstrated.
