Abstract
An optically fed lens array radar system is provided with an on boresight ed and a plurality of off boresight feeds. When looking far enough off boresight, one switches from the on boresight feed to the appropriate off boresight feed. The off boresight feeds simultaneously cover a large scan angle and achieve with the on boresight a large bandwidth over the largest scan angle of interest.
