Radar Change Detection in the Time Domain

We develop novel wave scattering principles and illustrate their application to the important problem of detecting changes or scatterers in a general background medium. The derived theory and algorithms are developed directly in the time domain, and are applicable to the analysis and processing of pulsed radar data. Envisioned applications include the detection and localization of silent threats, e.g., intrusion detection, in indoor facilities, tunnels, and caves. Of particular interest is the detection of changes in areas where radar surveillance is necessary due to practical inaccessibility via other sensing modalities such as video cameras.
