Abstract
A method and apparatus for resolving a radar return by an object or layer below the earth's surface from a radar return of an air-to-earth interface. More specifically, a method and apparatus for generating short pulsewidth, broad bandwidth RF signals and for effecting control and timing of transmitted and received radar signals in order to focus an antenna illumination pattern. The apparatus includes an antenna array including a plurality of antenna elements which transmit and receive the RF pulsed signals and a custom control module which generates the control signals fed to the antenna array to delay the RF pulse signals with respect to each other, upon transmission and receipt, in order to form transmit and receive antenna illumination patterns.
