A transponder consisting of two antennas and an amplifier allows a ground-based synthetic aperture radar to operate as a bistatic system. In such a way, it is able to detect two displacement components of targets in its field of view. An enhanced transponder is proposed. Its special features are (i) cross-polarised antennas and (ii) antennas separated by a long RF cable (35 m). This transponder is able to provide 82 dB gain without triggering auto-oscillations. Monostatic and bistatic images have been obtained in an urban scenario.

Abstract
A transponder consisting of two antennas and an amplifier allows a ground-based synthetic aperture radar to operate as a bistatic system. In such a way, it is able to detect two displacement components of targets in its field of view. An enhanced transponder is proposed. Its special features are (i) cross-polarised antennas and (ii) antennas separated by a long RF cable (35 m). This transponder is able to provide 82 dB gain without triggering auto-oscillations. Monostatic and bistatic images have been obtained in an urban scenario.
