Spatial digital processing: Application to radar antennas

Recent improvements of fast processors and microwave components, and their expected applications in the radar domain, open the way to the realization of digital beam forming antennas. A lot of advantages can be expected from the use of that kind of antenna. Many needs and requirements of radar systems are satisfied : jamming cancellation, environmental adaptivity, beam shaping...Our research about digital beam forming is aimed at estimating the performances of such equipment and designing architecture and element specifications.
