Abstract
An interference-aided navigation system for a rotating vehicle provides rotation angle estimates using interference or jamming signals. An antenna receives interference signals and desired navigation signals. A RF processing function connected to the antenna processes the received interference signals and the desired navigation signals into IF signals. An A/D converter connected to the RF processing function digitizes the interference signals and desired navigation signals and to provide a digitized IF signal. A tracking filter tracks amplitude variations of the interference signals and provides the rotation angle estimate signal of the rotating vehicle.
