1. A method for operating a synthetic aperture radar, SAR, mode, in an SAR instrument, wherein the method comprises the steps of:
acquiring at least one subswath positioned in an across track direction of a movement of the SAR instrument, wherein the at least one subswath is acquired at a predetermined radio frequency bandwidth;
adjusting one or more of (a) the predetermined radio frequency bandwidth, (b) a number of parallel simultaneous subswaths and (c) an inserted burst duration for a further subswath based upon a predetermined parameter; and
constructing an SAR image based on the acquired at least one subswath.
