Optical-Theorem-Based Coherent Scatterer Detection in Complex Environments
A new approach is proposed to detect scatterers embedded in reciprocal media from scattering data. The new method is rooted on physical considerations, in particular, on the optical theorem applicable to wavefields (e.g., acoustic, electromagnetic, and optical).

| description | A new approach is proposed to detect scatterers embedded in reciprocal media from scattering data. The new method is rooted on physical
considerations, in particular, on the optical theorem applicable to wavefields (e.g., acoustic, electromagnetic, and optical). The approach exploits
insight gained from the optical theorem which assigns physical energy interpretations to the wave data from time reversal mirrors and cavities
from which one can deduce the presence of unknown scatterers in unknown background media. The proposed approach is ideally suited for
target detection in complex, highly reverberating unknown environments
such as indoor facilities, caves, tunnels, and urban canyon. |
