Abstract
A navigation system and method for guiding a vehicle with respect to a source of jamming is disclosed, the system and method being capable of receiving navigation-aid signals, detecting jamming of such signals, mitigating such jamming, determining direction to the source of jamming, and interdicting that source, e.g., a drone gun.
Claims20
A system for navigating with respect to at least one of navigation-aid signal and jamming thereof, comprising:
- an antenna array comprising a first antenna and a second antenna;
- wherein the first antenna is connected to a signal combiner via a first signal path, wherein the second antenna is connected to the signal combiner via a second signal path;
- wherein an output of the signal combiner is connected to a power detector;
- wherein the power detector is connected to a controller;
- wherein the controller is operable to determine a direction to a source of jamming;
- and
- wherein the controller is operable to home a vehicle in the direction of the source of jamming by steering the vehicle to maximize output power of the signal combiner.
A method for navigating with respect to at least one of navigation-aid signal and jamming thereof, comprising:
- connecting a first antenna of an antenna array to a signal combiner via a first signal path;
- connecting a second antenna of the antenna array to the signal combiner via a second signal path;
- connecting an output of the signal combiner to a power detector;
- connecting the power detector to a controller;
- determining, via the controller, a direction to a source of jamming;
- homing, via the controller, a vehicle in the direction to the source of jamming by steering the vehicle to maximize an output power of the signal combiner measured by the power detector;
- and
- navigating, via the controller, the vehicle in the direction to the source of jamming.
A system for navigating with respect to at least one of navigation-aid signal and jamming thereof, comprising:
- an antenna array comprising a first antenna and a second antenna;
- and
- a computer processor;
- wherein the first antenna is connected to a signal combiner via a first signal path, wherein the second antenna is connected to the signal combiner via a second signal path;
- wherein an output of the signal combiner is connected to a power detector;
- wherein the power detector is connected to a controller operable to home a vehicle in a direction to a source of jamming based on a power measured by the power detector;
- wherein the computer processor is operable to assess a current location of the vehicle relative to a desired location and/or track;
- wherein the computer processor is operable to instruct the vehicle to move so as to reduce a distance between the current location of the vehicle and the desired location or track;
- and
- wherein the controller is operable to switch between navigation of the vehicle via the computer processor and homing the vehicle via the controller.
