Completed TRL 2 (started at 2, targeting 4)
This work will develop a Global Hawk installation plan for a dual frequency (W- and Ka-band) radar that combines two existing Goddard radars, Cloud Radar System (CRS) and High Altitude Wind and Precipitation Imaging Radar (HIWRAP). The main part of the effort will focus on an implementation plan to reduce costs and risks for upcoming opportunities such as NASA Earth Venture (EV-3) and Aerosol Chemsitry Ecosystem (ACE) algorithm development activity.
The effort will involve a mechanical and thermal study for installation of CRS into the Global Hawk, RF design for integrating the HIWRAP Ka-band transceiver with CRS and a new subscale prototype antenna for ACE, and specification and testing of a Ka-/W-band radome necessary in front of the antenna. The proposed work will be a solid design concept for a dual-frequency CRS that can be readily implemented on the Global Hawk. Since CRS is currently single frequency (W-band) and the NGES antenna is dual-frequency (Ka- and W-band), this effort investigates what is necessary to use the HIWRAP Ka-band transceiver with CRS timing and other interfaces. Finally, the Global Hawk installation will require a dual-frequency radome and part of this effort will investigate suitable radome materials that is transparent at at both operating frequencies.
This instrument will benefit the ACE mission, both in development of the spaceborne radar and in pre-launch algorithm activity.
Listed on TechPort itself — the most direct way to ask about this specific project.
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.
