Radar cross section analysis is of increased importance either for tailoring of modern radars to their targets and environment (i.e. clutter), or for designing stealth vehicles. Equipment is currently operated for such purpose in the field, in large static facilities, or in smaller anechoic chambers with scale targets. The signal processing algorithms and hardware associated to the radar sensor have to fulfill the following requirements: high spatial resolution in either 1, 2 or 3 dimensions resulting from real, synthetic or inverse synthetic aperture processing, and pulse compression; high accuracy and sensitivity, related to specific calibration procedures; reasonable computing time and adequate display of the results. This presentation will mainly focus on the methodology and signal processing used for indoor target analysis: some specific requirements for accurate results will be first reviewed; the now classical inverse synthetic aperture radar (ISAR) imaging through rotating the target on a turntable will be then shortly described, and we will finally emphasize a light experimental set up for fix target imaging through synthetic aperture radar (SAR).
