Abstract
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 during at least one acquisition burst duration and/or at a predetermined radio frequency bandwidth; adjusting the at least one acquisition burst duration and/or the predetermined radio frequency bandwidth and/or a number of parallel simultaneous subswaths and/or an inserted burst duration for a further subswath based upon a predetermined parameter; constructing an SAR image based on the acquired at least one subswath.
Claims19
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.
A SAR instrument comprising:
- an acquisition unit configured to acquire 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;
- and
- a processing unit configured to adjust 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 configured to construct an SAR image based on the acquired at least one subswath.
