The proposal of this paper is the analysis of the use of vegetation
elements as a protective cover against radar detection, creating
radar invisibility in the region behind the cover. The shrub
canopies both absorb part of the radiated power, attenuating it in
the backscattering region, and scatter the rest of the power all
around their volumes, reducing the reflected signal towards the
