7. A method of producing a synthetic aperture radar image comprising:
-
transmitting an analogue signal from a space-borne or airborne transmitter to a surface to be imaged, reflecting the analogue signal from the surface to a space-borne or airborne analogue repeater, transmitting the analogue signal from the airborne analogue repeater to a ground based receiver, converting the analogue signal received by the ground based receiver into a digital signal, processing the digital signal to create the synthetic aperture radar image, wherein, the method is performed bistatically. - View Dependent Claims (8, 9, 10, 11, 12, 13)
