Phone Number: 7349264434

Explanation
Please explain in the area below why an STA is necessary:
SRI plans to continue testing of its experimental S-band radar system on a high altitude balloon over a six month period starting December 12th. A STA license is necessary to operate the radar while the balloon is airborne. A STA license is also required for the balloon-ground two-way communication link needed to control the radar and down-link data while the balloon is airborne. SRI is requesting permission to operate the radar system within a rectangular area around Crestview, FL at altitudes up to 65000 ft. This zone of operation is bounded by 29.25N 89W in the southwest corner and 32N 83.5W in the northeast corner. The experiment is expected to be conducted between December 12th 2019 and June 11th 2020.

Purpose of Operation
Please explain the purpose of operation:  Testing an experimental S-band radar system on a high-altitude balloon. The radar system is designed to generate synthetic aperture radar (SAR) and interferometric synthetic aperture radar imagery for the purpose of measuring land deformation. The radar will operate periodically while the balloon is airborne.

Certification
Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.
