An RF emitter sensing device is provided comprising an antenna circuit and an estimator configured to output, for one or more incoming signals-of-interest (Sol), either or both of an estimated range to the emitter of each Sol, and estimates for one or more angles corresponding to the 3D angle-of-arrival (AoA) of each Sol, wherein: the antenna circuit has a plurality of ports that each output an output signal containing the one or more Sol, the antenna circuit 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 Sol, in a common volume of space. |
