Abstract of the Disclosure The test equipment for a synthetic aperture radar (SAR) system Is provided with an input and output connector (6) and Is composed of a signal loop (3) arranged between the input and output connector (6) and electromagnetically reproduces these pulses or signals (4) emitted from a SAR system (2) in the absence of a SAR antenna (18). The input connector (6) is electrically connected with a circulator (5) which Is integrated into the signal loop (3) and which combines the incoming and outgoing pulses or signals (4) to and from the SAR system (2), The signal loop (3) is composed of a forward branch (7) and a backward branch (1 0), the forward branch (7) being composed of a multitap time- delay and reproducing different travel times of the pulses or signals (4), while the backward branch (10) in the form of a bus (9) combines the delayed pulses or signals (4). The ends of the forward and back- ward branches (7 and 10) are terminated by their wave Impedances (11, 12) and between them is arranged a crossbar matrix (13) onto which can be set the point target modules (14).
