Abstract

This paper describes a compact, high speed 95 GHz scanned antenna designed for collecting radar data from an airborne platform. This antenna consists of a corrugated horn feeding an f∶1 parabolic reflector through a hole in the scanning mirror, as shown in Figure 1. Radiation exiting the horn is thus collimated by the parabola and is incident on the flat scanning mirror, from whence it is steered to the desired angle. The collimated output is incident on the scanner in such a way that the angle is doubled, so that greater angular coverage can be obtained for a given mirror angular velocity. The scanner operates in only one axis; coverage of the other dimension is given by the forward motion of the aircraft.
