Best Contact
Give the following information of person who can best handle inquiries pertaining to this application:  
Last Name: Bonilla
First Name: Eliud
Title: Senior Staff
Phone Number: 2402285853

Explanation
Please explain in the area below why an STA is necessary:
The Johns Hopkins University Applied Physics Laboratory (JHU/APL) is working on developmental radar signal processing algorithms. As part of this process it needs temporary on-air transmission/reception to account for atmospheric and propagation effects. We estimate on-air activities should not exceed a three month period.

Purpose of Operation
Please explain the purpose of operation:  Radar signals will be emitted towards a target in low earth orbit in order to calibrate and optimize developmental signal processing algorithms. Bistatic and monostatic configurations are planned.

Information
Callsign: WM9XOX
Class of Station: FX
Nature of Service: Experimental

Requested Period of Operation
Operation Start Date: 06/01/2018
Operation End Date: 08/31/2018

Manufacturer
List below transmitting equipment to be installed (if experimental, so state) if additional rows are required, please submit equipment list as an exhibit:  
Manufacturer Model Number No. Of Units Experimental

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.

Is a directional antenna (other than radar) used?   Yes
Exhibit submitted:   Yes
(a) Width of beam in degrees at the half-power point:   0.50
(b) Orientation in horizontal plane:  
(c) Orientation in vertical plane:  
Will the antenna extend more than 6 meters above the ground, or if mounted on an existing building, will it extend more than 6 meters above the building, or will the proposed antenna be mounted on an existing structure other than a building?   Yes
(a) Overall height above ground to tip of antenna in meters:   30.00
(b) Elevation of ground at antenna site above mean sea level in meters:   132.00
(c) Distance to nearest aircraft landing area in kilometers:   18.00
(d) List any natural formations of existing man-made structures (hills, trees, water tanks, towers, etc.) which, in the opinion of the applicant, would tend to shield the antenna from aircraft: The antenna to be used is the 60 diameter parabolic dish/system. It has been in use since 1963 with several upgrades, operating now in S/X-bands in support of various NASA space missions. Impact to aviation is mitigated in several ways including shutting off transmissions when antenna is pointing below 10 deg elevation (minimize impact on airport systems), no transmissions in aviation bands, and a 0.5 deg 3dB beamwidth. (see Antenna Drawing" exhibit).
