Two-dimensional scanning cylindrical reflector

A computerized device comprising at least one hardware processor configured to:

• scan along a straight edge of a parabolic cylindrical reflector by electronically adjusting a phase of each of a plurality of antenna feeds, thereby changing the incident angle of an energy beam relative to the vertex line of said parabolic cylindrical reflector, wherein said plurality of antenna feeds are positioned in a line-array parallel to a focal line of said parabolic cylindrical reflector, wherein said line-array is substantially centered opposing said parabolic cylindrical reflector;
• scan along a curved edge of said parabolic cylindrical reflector by at least one of:
• (a) moving said plurality of antenna feeds, using a mechanical positioning mechanism, in a direction parallel to a directrix of said parabolic cylindrical reflector while maintaining said positioning, and transferring heat produced by said line-array to said mechanical positioning mechanism, and
• (b) electronically selecting one of a plurality of parallel line-arrays, wherein each of said plurality of parallel line-arrays maintains said positioning;
• and
• output scanned data.
