Characterization of the Effects of Cavities and Canopies on Radar Target Signatures

Abstract

I conducted a literature search on electromagnetic models for cavities and canopies and their effect on radar target signatures. This report is a simple analysis of cavities as well as a review of electromagnetic codes that simulate the radar backscatter of targets with cavities. I also review imaging and parametric techniques to describe targets with cavities and canopies. Finally, recommendations are offered for enhancing signature generation for hardware-in-the-loop (HWIL) and software-in-the-loop (SIL).
