This work develops the high-fidelity simulation capability for low-frequency synthetic aperture radar (SAR) imaging of complex scenes including both metal and dielectric regions. The simulation is based on a Method of Moments (MOM) numerical electromagnetic analysis of scenes where metal targets are obscured by foliage modeled as dielectric. 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 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 low-frequency SAR applications for the prediction of target signatures under various conditions of concealment.
