An interference-aided signal acquisition and tracking system with temporal beam forming for a rotating vehicle enhances signal to noise ratio 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 provides a digitized IF signal. A tracking filter tracks amplitude variations of the interference signals and provides a rotation angle estimate signal of the rotating vehicle. A signal modulation function connected to the tracking filter and the A/D converter varies gain of the IF signal to enhance the signal to noise ratio.
