Abstract

Receiver apparatus for receiving electromagnetic target radiation polarized in a first direction includes a dielectric lens having forward and rearward surfaces. The received target radiation is refracted at the forward surface and reflected by the rearward surface. An antenna array is disposed adjacent one of the forward and rearward surfaces for receiving (a) the target radiation reflected from the rearward surface, and (b) a local oscillator beam haivng a polarization direction which is orthogonal to the polarization direction of the target radiation received at the antenna array.
