Please explain in the area below why an STA is necessary:
Experiment duration will be less than 6 months, and thus we have been directed to use Application for Special Temporary Authority in lieu of the Form 442 Filing Option.

Purpose of Operation
Please explain the purpose of operation:  Operation of a low-power imaging radar system developed by Umbra Lab LLC. It is designed for operation an airborne platform but experimental testing may also be performed on mobile platforms. The purpose of the radar system, and the rational for this STA, is to 1) demonstrate hardware and functionality necessary for a planned space-based synthetic aperture radar, and 2) gather imaging radar data pertinent to the operation of a space-based synthetic aperture radars operating within the ITU allocated frequencies at X-band.

Class of Station: MO
Nature of Service: Experimental

Requested Period of Operation
Operation Start Date: 05/01/2017
Operation End Date: 10/01/2017

Is a directional antenna (other than radar) used?   Yes
Exhibit submitted:   Yes
(a) Width of beam in degrees at the half-power point:   25.00
(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:   2500.00
(b) Elevation of ground at antenna site above mean sea level in meters:  
(c) Distance to nearest aircraft landing area in kilometers:   1.00
(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: While operating on a test aircraft the transmit antenna will be pointed at the ground with a grazing angle of 45 degrees, such that the majority of the emitted power will be directed toward the ground immediately adjacent to the aircraft.
