Special Temporary Authority application - Explanation

Please explain in the area below why an STA is necessary:
An STA is necessary to permit experimental testing of a short-range maritime radar, the Garmin Fantom 18x, to evaluate its viability as a detect-and-avoid (DAA) aircraft collision avoidance system. This temporary authorization will allow Rainmaker to test the system across multiple operating locations to detect and track uncooperative aircraft within the National Airspace System (NAS). The experimental testing period is required to validate the systems capabilities against RTCA DO-381 and ASTM F3442-25 standards. If these initial validations are successful, the STA will have facilitated the necessary testing to undergo further development and coordination with an FAA BEYOND UAS test site.

Special Temporary Authority application - Purpose of Operation

Please explain the purpose of operation:
The primary objective of this experiment is to evaluate the viability of a short-range maritime radar (Garmin Fantom 18x) as a detect-and-avoid (DAA) aircraft collision avoidance system. Rainmaker intends to validate this highly mobile, cost-effective alternative against legacy DAA systems. The operation will test the X-band radars ability to detect targets through common aerial obscurities, such as light fog and cloud cover. Validating this experimental setup serves a significant public interest by advancing aviation safety, adding crucial detection capabilities to our uncrewed fleet, and facilitating proper FAA flight authorizations for our drought-relief cloud seeding operations.
