Microwave imaging of antenna RCS sources

Microwave metrology of antennas is widely established for commissioning, quality assurance and diagnosis. Conventional schemes utilise the antenna as an active device in either transmit or receive mode. In a new approach to imaging structure the authors have studied the antenna as a passive scatterer from the point of view of its RCS. In this mode, the antenna response to an incident wavefront is dependent on its load.<
