Abstract: A detection system includes a phased array antenna having unitary radiating elements, the system being suitable for, in each cycle, successively directing, by way of the successive application of a first and a second determined phase law to the electrical signals for supplying power to the array antenna, the antenna radiation towards a first target area (Z1), then a second target area (Z2), which is separate from the first target area (Z1), and determining an image of each target area (Z1) on the basis of the echoes received from each of the first and second target areas.

Abstract: The SAR is provided formed from a plurality of elementary images issued from successive emission spots, the elementary images overlapping zones of overlap, the measurement of the off-pointing is carried out on the basis of the difference between the energies received from two successive spots in a zone of overlap, the compensation being applied to the antenna reception gain in light of the measurement.
