Abstract

The U.S. Army Research Laboratory (ARL) recently designed and tested a new prototype radar, the Spectrally Agile Frequency-Incrementing Reconfigurable (SAFIRE) radar system, based on a stepped-frequency architecture to address challenges when operating under spectrally congested and spectrally restricted RF environments. SAFIRE is a vehicle-based, low-frequency, ultra-wideband (UWB) synthetic aperture radar (SAR) with frequencies spanning from 300 MHz to 2 GHz, where many frequency bands within this spectrum are either employed by other systems (congested RF environment) or prohibited (spectrally restricted RF environment). In this paper, we present recent SAFIRE stepped-frequency radar data collected from an arid test site, the adverse effects of SAR under congested and spectrally restricted RF environments to SAR imagery, and the application of our spectral information recovery technique to mitigate artifacts.
