ABSTRACT:
The present invention provides a small-size image radar apparatus to be mounted on an aircraft, having a high resolution not only the flying direction but also in the direction vertical to the flying direction. The image radar apparatus comprises a transmission antenna 2, a plurality of independent reception antennas 5.sub.1, 5.sub.2, and a computer 10 for simultaneously executing a two-dimensional phase synthesis. The synthesis result is obtained as a two-dimensional image.
