Explanation
Please explain in the area below why an STA is necessary:
The applicant seeks an STA to operate an experimental X-band radar system being developed by the Georgia Tech Research Institue for the United States Missile Defense Agency (MDA) to support multipath data collection efforts against low flying, unmanned targets. The system consists of a single transmitter equipped with a 32 dBi parabolic reflector antenna and a receive array comprised of 4 parabolic reflector antennas that are co-located with the transmitter system. The transmitter contains a TWT with a peak power of 2 kW and a maximum duty cycle of 6%. The system will be located on the Santa Rosa Island test range associated with Elgin Air Force Base. Once installed at the test site, the system supports a manual change in the elevation pointing angle from +10 degrees (forward) to -20 degrees (backward) as measured from vertical. The elevation angle and azimuth angles are fixed during a data collection event. The radar system will transmit a pulse train at a fixed pulse repeitition frequency chosen between 1 kHz and 10 kHz. A linear frequency modulation is applied intra-pulse. The swept bandwidth is 25 MHz, and the pulse duration is selectable between 1 and 8 microseconds. The transmitter is designed to operate with a center RF frequency between 9.5125 GHz and 10.4875 GHz. The transmitter is located on a base with the top of the transmit antenna positioned 1.35 meters above the surface in the zero degree elevation tilt configuration. The test site on which the radar system will be located is approximately 11 ft about mean sea level. GTRI will be working with the Eglin 46th Test Wing to address frequency deconfliction at the test range. The system will be oriented in order to radiate toward test targets flying over the ocean.

Purpose of Operation
Please explain the purpose of operation:  Operation of an experimental X-band radar system to support multipath data collection efforts against low flying, unmanned targets. The experimental program will support the development of techniques that enable the estimation of target elevation angles in the presence of low elevation angle multipath.

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.
