Novel Polarimetric SAR Interferometry Algorithms, Phase II
Completed
Description
Polarimetric SAR interferometry (PolInSAR) is a recently developed synthetic aperture radar (SAR) imaging mode that combines the capabilities of radar polarimetry and interferometry, as well as adding new capability from a synthesis of the two techniques. PolInSAR holds the promise of being able to provide unique data that can be of great value to the earth science community. By observing scattering volumes such as vegetation canopies, ice sheets, and dry soils using this new SAR technique, one can obtain and decompose scattering from within that volume. In traditional SAR imaging, all scattering that arises from within a three-dimensional resolution cell of the volume is collapsed into a single pixel value due to the layover effect. PolInSAR provides a method of separating the various scattering center locations based on their polarimetric properties. PolInSAR techniques, therefore, can address many issues of interest to the vegetation and environmental community, providing measurements of foliage structure and density, and potentially contribute directly to our understanding of the carbon cycle budget.

How to get involved
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
