Abstract
The corner reflector concept in remote sensing is discussed. The specularity of the energy return from the corner reflector concept requires that the trunk-ground angle departs from the normal by less thanλ/sinΘi, typically less than 1°. This study has shown that scatter pattern is multilobed, and that an angular deviation of about ±3° from specular range would still cause most of the scattered energy to return to the radar from the main specular lobe.
