Abstract: The invention relates to a target characterisation method for a detection device of multi-panel radar or sonar type with electronic scanning, comprising the steps of:



generating a plurality of pulses on a plurality of antenna panels (PE1, PE2, PE3) of the detection device according to a temporal and angular interleaving pattern, so as to perform a scan over all of the relative bearing domain of the detection device;
generating a plurality of detection maps, by the acquisition of a plurality of observations combined with one another by coherent or non-coherent integration of the echoes corresponding to the plurality of pulses, each detection map being obtained in a given direction (EL1, EL2, EL3) corresponding to the width of the main lobe of the antenna panel;
combining the detection maps so as to detect a presence of a target in the relative bearing domain of the detection device.

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.
