US12560410 - Devices, systems, and methods for countering drone countermeasures
This patent describes a navigation system for vehicles that can detect and mitigate jamming signals, particularly from drone countermeasures, by utilizing an antenna array and a guidance control system. The system is designed to calculate the direction to the jamming source and navigate the vehicle accordingly, enabling effective target interdiction.
Claim 1
1 . A vehicle having a system for navigating with respect to at least one of navigation-aid signal and jamming thereof, comprising: an antenna array including a first antenna, a second antenna, and a third antenna, each responsive to jammer burdened navigation signals, the first antenna being connected to a signal combiner via a first signal path, the second antenna also connected via a second signal path, and the third antenna also connected via a third signal path to the signal combiner, the combiner output being connected to a power detector that is also connected to a receiver and to a guidance navigation and control type controller that is further connected to at least one element of the first signal path, the first signal path integrating at least one of a phase rotator and a tunable delay line, the controller being any type that is operable to calculate a delay value of the tunable delay line based on a time difference of arrival (TDOA) among the first signal path, the second signal path, and the third signal path, the controller being any type that is operable to determine at least one vehicle parameter of position, velocity and attitude with respect to at least one of the Earth and a source of jamming, and the controller being any type that is operable to determine direction to a source of jamming and navigate a vehicle in that direction, as means of providing at least one of guided navigation, jammer mitigation, source-relative transit, and target interdiction, wherein the controller is operable to steer the vehicle with respect to the source of jamming by maneuvering to minimize or maximize an output power of the signal combiner. an antenna array including a first antenna, a second antenna, and a third antenna, each responsive to jammer burdened navigation signals, the first antenna being connected to a signal combiner via a first signal path, the second antenna also connected via a second signal path, and the third antenna also connected via a third signal path to the signal combiner, the combiner output being connected to a power detector that is also connected to a receiver and to a guidance navigation and control type controller that is further connected to at least one element of the first signal path, the first signal path integrating at least one of a phase rotator and a tunable delay line, the controller being any type that is operable to calculate a delay value of the tunable delay line based on a time difference of arrival (TDOA) among the first signal path, the second signal path, and the third signal path, the controller being any type that is operable to determine at least one vehicle parameter of position, velocity and attitude with respect to at least one of the Earth and a source of jamming, and the controller being any type that is operable to determine direction to a source of jamming and navigate a vehicle in that direction, as means of providing at least one of guided navigation, jammer mitigation, source-relative transit, and target interdiction, wherein the controller is operable to steer the vehicle with respect to the source of jamming by maneuvering to minimize or maximize an output power of the signal combiner.
