Co-notch and independent windowing to mitigate interference in SAR-based imagery

A method, comprising:

• generating windowed synthetic aperture radar (SAR) data based upon:
• applying a first window function to a first set of samples in a first SAR dataset, the first SAR dataset corresponding to a first SAR scan of a scene;
• and
• applying a second window function to a second set of samples in the first SAR dataset;
• and
• generating a coherent image product based upon the windowed SAR data and a second SAR dataset, the second SAR dataset corresponding to a second SAR scan of the scene, the windowed SAR data and the second SAR dataset being co-notched such that the first windowed SAR dataset has zero-valued samples at locations corresponding to zero-valued samples in the second SAR dataset.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, perform the following acts:

• responsive to receiving first and second SAR datasets corresponding to SAR scans of a scene at first and second respective times, co-notching the first and second SAR datasets;
• generating windowed SAR data based upon:
• applying a first window function to a first set of samples in the first SAR dataset, the first window function matched to a size of the first set of samples;
• and
• applying a second window function to a second set of samples in the first SAR dataset, the second window function matched to a size of the second set of samples;
• and
• generating a coherent image product based upon the windowed SAR data and the second SAR dataset.
