Indoor time domain RCS measurements and ISAR imaging without anechoic chamber

RCS measuring in time domain opens wide possibilities for interesting applications. Using of the short impulses as test signals enables to do RCS measurements in wide frequency band. In this paper, time domain method is presented which let to overcome many measurement problems: signal leakage through antennas, occasional reflection from the walls, and ceilings of the room. It leads to create good quality ISAR imaging without expensive anechoic chamber.
