Synthetic aperture (SA) imaging techniques are considered for identifying targets at ranges of a few kilometers using near-millimeter waves. A generalized concept of SA imaging is presented. A hybrid SA array technique is proposed that would significantly diminish the motion required for the SA data generation. A scanning SA technique is presented and analyzed in detail. Images are shown that were generated using the scanning SA technique with a near-millimeter wave homodyne system operating at 1.22 mm.
