SoOp verification for Rydberg MW sensor - Demonstration of multi-frequency (L and S band) radar remote sensing using a quantum Rydberg receiver instrument (IIP-24)

Objectives for technology investment: • Snow Depth and Snow Water Equivalent Targeted Observables for Earth System Explorer • Snow measurement in mountain snow (P-L band) • Surface Topography and Vegetation for Decadal Survey Incubation • Vegetation water content profiling (vertical profiling with multi-frequency P-Ka band signals) • Soil moisture depth profiling (depth profiling to root zone soil moisture with multi-band I/VHF-C band) • Focus area: Coupling of the water and energy cycles Key technology needed to invest in the next decade: • Verification of multi-frequency SoOp (P-S band) for Quantum Rydberg Sensors • Compact software Defined Radio based back-end capable of pairing with Quantum Rydberg Sensors for digitizing and processing multi-frequency signals • TRL 4 to TRL 5

Increase scientific understanding of natural phenomena using remote sensing.

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
