Abstract:
1. A material detection system comprising: a sensor system configured to collect radiation from a region of interest; and a processing unit configured to decompose the collected radiation into natural resonance signals, to analyze the natural resonance signals to identify poles and a residue in the natural resonance signals, to implement an algorithm to extract an observation angle of the collected radiation based on characteristics of the poles and the residue in the natural resonance signals, and to detect an anomaly corresponding to a concealed dielectric material based on calculating at least one dielectric constant associated with the concealed dielectric material based on wave characteristics of the natural resonance signals and based on the extracted observation angle, and to identify the dielectric material by comparing the at least one dielectric constant with dielectric constant data stored in a database.
