Scattering Analysis of Polarimetric Inverse SAR Image using Scale Model under Vegetation Canopy

Radar scattering of the hidden object under the canopy of vegetation or soil is difficult to verify without priori information of the target. A scale model of the manmade structure is deployed and measured to verify the phenomenon of the scatterer and the effect of the vegetation canopy. Full polarization inverse synthetic aperture radar (ISAR) imaging is captured using C-band for each model. A two-dimensional polarimetric image is decomposed and its independent scattering is analyzed. It is shown that the C-band wavelength can penetrate vegetation canopy. While it is difficult to distinguish using visual images, it is shown that vegetation canopy contributes to reducing total received power by 2.7 dB. The experiment result of ISAR on scale model shows that it is coherent with the phenomenon of scattering and is a potential method to validate real SAR targets.
