The report details the Recursive Sidelobe Minimization (RSM) technique (patent pending), which was integrated with the standard SAR image formation algorithm to achieve a significant reduction in sidelobes and noise in the resulting SAR imagery.
RFI-radar signal separation via simultaneous low-rank and sparse recovery
This paper presents a simple adaptive framework for robust separation and extraction of multiple sources of radio-frequency interference (RFI) from raw ultra-wideband (UWB) radar signals via…

The authors employ a sequence of directional filters to the SAR imagery, thereby generating a series of subaperture images that recover the directional dependence of the target scattering, and design a hidden Markov model (HMM) wherein the orientation-dependent scattering statistics are exploited explicitly.
Efficient and Robust RFI Extraction Via Sparse Recovery
This paper presents a simple adaptive framework for robust separation and extraction of multiple sources of radio-frequency interference (RFI) from raw ultra-wideband (UWB) radar signals in…
Obstacle avoidance and concealed target detection using the Army Research Lab ultra-wideband synchronous impulse reconstruction (UWB SIRE) forward imaging radar
The U.S. Army Research Laboratory conducted an experiment this winter at Aberdeen Proving Ground to support the phenomenological studies of the backscatter from positive and negative obstacles for autonomous robotic vehicle navigation, as well as the detection of concealed targets of interest to the Army.
