METHOD FOR RECONSTRUCTING AN IMAGE OF A SCENE

The present invention relates to a method for reconstructing an image of a scene using an antenna system and comprising, for each pixel of the image: a. receiving samples of wide-band time-domain signals backscattered by reflectors of the scene; b. for each direction among a plurality of directions, determining, based on the received samples, new samples of a new time-domain signal associated with said each direction, respectively, each new signal corresponding to a wide-band plane wave in said each direction, respectively; c. for each direction among the plurality of directions, selecting, from the new samples of the respective new time-domain signal, samples corresponding to a there-and-back path time of said new signal from an origin of the image to said each pixel; and d. determining a light intensity of said each pixel based on delayed samples.
