FOPEN scene generation using numerical electromagnetic analysis

This work develops the high-fidelity simulation capability for foliage penetration (FOPEN) synthetic aperture radar (SAR). The simulation is based on a method of moments (MOM) numerical electromagnetic analysis of target scenes including foliage. The ability to accurately model the interaction of foliage and target is crucial for an accurate simulation. Example scenes for isolated metal targets are provided in addition to scenes with dielectric and combined metal and dielectric targets. As expected, the effect of the surrounding foliage is shown to have a significant impact on the reconstructed target image. This approach will be useful in FOPEN applications for the prediction of target signatures under various conditions of concealment.
