Polarized radio frequency (rf) roll, pitch and yaw angle sensors and orientation misalignment sensors

Abstract

A cavity sensor including: a body defining a cavity, the cavity having an opening on one end and a closed surface on other end; a reflective surface disposed in the cavity, the reflective surface being angled 45 degrees relative to a propagation direction of an incoming wave through the opening; and first and second angle probes positioned on each of two ends of the reflective surface. Also provided is a cavity sensor including: a body defining a cavity, the body having two or more conduits, each having an opening, the body having a closed surface opposing the openings, and a probe positioned in the cavity at a position common to each of the two or more conduits.
