Abstract
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 (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 circuit has a plurality of ports that each output an output signal containing the one or more SoI, 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 SoI, in a common volume of space.

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:
- receiving the output signals from the antenna, and
- generating 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.
An RF emitter sensing device comprising:
- an antenna;
- an isolation element;
- and
- an estimator configured to output, for one or more incoming signal-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 angle-of-arrival (AoA) of each SoI,
- wherein:
- the antenna includes 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

- such that the one or more E-field signals and the one or more H-field signals can be isolated from each other by combining the output signals;
- and
- the isolation element is configured to output one or more isolated SoI outputs, for each respective port by
- receiving the output signals from each output port of the antenna, and isolating in each respective port, one or more SoI from other extraneous signals;
- 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:
- receiving the output signals from the isolation element, and
- generating 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.
