Claim Text:
1. An RF emitter sensing device comprising an antenna and an estimator configured to output, for one or more incoming signals-of-interest (SoI), either or both of an estimated range to the emitter of each SoI, and estimates for one or more angles corresponding to the 3D angle-of-arrival (AoA) of each SoI, wherein: the antenna has a plurality of ports that each output an output signal containing the one or more SoI, the antenna including one or more multi-port antennas, each multi-port antenna having two or more ports, each multi-port antenna being configured to pick up a combination of one or more E-field signals and one or more H-field signals from each SoI, at a common point in a common volume of space; and the estimator is configured to output either or both of an estimated range to the emitter of each SoI, and estimates for one or more angles corresponding to the AoA of each SoI by:
