Abstract

A triple-mode monopulse tracking antenna and antenna system with risley prism beam steering. In particular, a monopulse tracking antenna, comprising: a triple-mode circular waveguide horn, configured to generate three monopulse patterns; at least two Risley prisms, each positioned a fixed distance from the triple-mode circular waveguide horn, configured to receive and steer the three monopulse patterns, wherein each Risley prism is coated with an anti-reflective layer; a means for axially rotating each of the at least two Risley prisms; and a parabolic phase correcting surface, positioned intermediately between the triple-mode circular waveguide horn and at least two Risley prisms.
