Abstract
A steerable antenna or scanner assembly ( ) is connected to signal process means ( ). A housing ( ) surrounds a focusing antenna ( ) which is stationary relative to the housing ( ), a polarisation rotator ( ), a steerable reflector ( ) angularly movable about a pivot axis ( ), and a detector ( ). Incoming radiation passes through the focusing antenna ( ), has its polarization altered as it passes through rotator ( ), reflects off reflector ( ), Passes through rotator ( ) again, encounters the antenna ( ) again and this time reflects off it to focus down, passes through rotator ( ) again, encounters the steerable reflector ( ) again and this time passes through it to reach the detector ( ). Moving the reflector ( ) angularly steers the directional sensitivity of the assembly ( ).
