There are different research and development lines focused on
reducing the radar probability of detection, aiming for radar invisibility.
Complex synthetic materials, multifaceted surface designs
or radar absorbing materials (RAM) are only some of the stealth
techniques used nowadays. Their objectives can be to deflect radiation,
to absorb the maximum percentage possible of the impinging
radar signal, and/or to scatter the electromagnetic energy,
reducing the fingerprint of the target in the radar direction. All
those options inspire the proposal of this paper: When using vegetation
masses as a shielding technique, canopies will absorb part
of the radiated power, attenuating the incoming signal in the
backscattering region, and they will spread the rest of the power
around their volume, reducing the signal reflected towards the
radar receiver.
