A pair of radar nodes, each with full azimuthal coverage, cooperate to identify the position of an object without explicit measurements of the object's azimuthal coordinate. A first radar node, operating within a first azimuth field of view (FOV), measures a first elevation angle and a first slant range of the object. A second radar node, operating within a second azimuth FOV, measures a second elevation angle and a second slant range of the object. The second radar node transmits the data to the first radar node, which identifies, based on the first and second azimuth FOVs, an object half space within which the object is located. The first radar node then calculates the position of the object without an ambiguous solution. Alternatively, the first radar uses the first and second azimuth FOVs to identify and reject the ambiguous solution.
