Abstract
The invention relates to a circuit for generating and/or detecting a radar signal for synthetic aperture radar in which the radar signal is subdivided into N sub-bands which are processed in parallel in N processing channels, each having a first mixer for processing in-phase signals, and a second mixer for processing quadrature signals. In the circuit the mixers of the N processing channels are in the form of identical mixer modules each comprising at least one mixer, and each module is associated with at least one external element for adjusting the mixer module in correspondence with the sub-band with which it is associated.
