Abstract: Systems, methods, and non-transitory media are provided for cross-coupling modeling and compensation. An example method can include determining one or more cross-coupling coefficients representing electrical cross-coupling within a component of a phased array antenna, wherein the component of the phased array antenna includes one or more signal paths between one or more beamformers of the phased array antenna and a set of antenna elements of the phased array antenna; based on the one or more cross-coupling coefficients, modifying one or more beamforming weights calculated for one or more signals routed via the one or more signal paths, wherein the modified one or more beamforming weights compensate for the electrical cross-coupling effect within the component of the phased array antenna; and applying, by the one or more beamformers, the modified one or more beamforming weights to the one or more signals routed via the one or more signal paths.
