Although modern airborne and space-borne SAR instruments have increasingly high resolution, and the images contain more and more detail, detecting and identifying small objects in SAR images is unreliable. Hence, there is a need for artificial radar tags to guarantee reliable detection and unambiguous identification. The paper describes a concept for a miniature SAR transponder and the important technology developments needed, specifically the signal delay circuitry and the antenna. The design of a practical transponder is discussed.
