Paper Abstract

The previous work demonstrate that detection based on the Laguerre transform exploits the 1D resonance response of the metallic target in the ultra wideband (UWB) synthetic aperture radar (SAR) images. The success is mainly due to the fact that Laguerre function space captures the information contained in the resonant response. However, in that case, only 1D resonance response information were utilized. In this paper, a new CFAR statistics based on spatial resonance templates is proposed. Based on the GLRT, the new CFAR statistics is formulated using the spatial extent of targets' resonance responses in the UWB SAR scenario. In the end, we show that the proposed CFAR statistics yields more robust detection.
