Last Name: Ericson
First Name: Eric
Title: Principal Investigator
Phone Number: 240-228-8521

Explanation
Please explain in the area below why an STA is necessary:
JHU/APL is under contract with the Navy to develop and field a low power, dual-band (X and Ka) radar system for making environmental measurements. An STA is being sought to allow for engineering checkout and long-term testing of the system.

Purpose of Operation
Please explain the purpose of operation:  The primary purpose of the experiment is to improve the Navy’s understanding of the environmental dependence of radar scattering from the ocean surface. The radar system is a new development and will need to undergo functional engineering testing involving radiating over a period of one or two days in both bands at JHU/APL facilities in Laurel, MD as well as a test facility near Chesapeake Beach, MD. Once testing is complete and the system is working as intended, it will be deployed on Frying Pan Tower in the Atlantic Ocean for a period of 75 days in order to capture a wide variety of environmental conditions.

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.
