Low-profile monopulse tracker

A monopulse tracker comprising:

• a housing having a first surface that extends along a plane defined by a first axis and a second axis, a first set of side surfaces that extend from opposing sides of the first surface at an acute angle from the first axis, and a second set of side surfaces that extend from opposing sides of the first surface at an acute angle from the second axis, the first surface and each side surface in the first set and the second set including a monopulse antenna system such that the monopulse tracker includes five monopulse antenna systems;
• circuitry configured to generate, for each of the five monopulse antenna systems, a set of ratios including an elevation ratio and an azimuth ratio such that five sets of ratios are generated;
• and
• a position estimator configured to receive the five sets of ratios and to estimate a position of an object based on the elevation ratio and the azimuth ratio in each of the live sets ratios.

A method for estimating a position of an object using a monopulse tracker that includes multiple monopulse antenna systems without steering the monopulse tracker, the method comprising:

• receiving a set of ratios including an elevation ratio and an azimuth ratio for each of two or more monopulse antenna systems that are positioned in the monopulse tracker in different orientations such that two or more sets of ratios are received;
• for each of the two or more sets of ratios, processing the elevation and azimuth ratios in the set to calculate a position of an object relative to a boresight angle of the respective monopulse antenna system such that two or more positions are calculated;
• and
• based on known orientation information defining a boresight angle of each of the two or more monopulse antenna systems, combining the two or more calculated positions to generate a single estimated position of an object in a field of view of the two or more monopulse antenna systems.
