ABSTRACT:
An airborne surveillance platform utilizes a low aspect ratio delta-shaped aircraft having a radar-transparent hull. The antenna is located within, and stationary relative to, the hull. The antenna comprises planar or linear phased arrays arranged to scan in a continuous 360 degree pattern in all azimuthal directions or in a continuous 180 degree pattern in all forward azimuthal directions. Planar phased arrays can be arranged to scan in a continuous pattern in the range from zenith to nadir or in portions of that range. In the case of forward direction scanning, the antenna arrays are located immediately inside the radar-transparent leading edges of the aircraft hull, thereby allowing a large cargo space within the hull between the antenna arrays. Access to the cargo space is provided through an opening in the trailing edge.
