Devices, systems, and methods for countering drone countermeasures

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,
• wherein the controller calculates the delay value to adjust the time difference of arrival (TDOA) to achieve a cancellation bandwidth (CBW), the cancellation bandwidth having a width of a jamming signal or a desirable signal;
• 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.
