A method for detecting RGPO/VGPO jamming

This paper proposes a general approach to detect the presence of deceptive counter measures such as RGPO or VGPO. The method which is based on the Kalman filter lays its foundation on drift between Doppler measurement and the Doppler information obtained from the range measurement of a target in track. By measuring this drift by Mahalonobis distance metric and comparing it with a predefined threshold; detection is performed. The performance of the proposed approach is illustrated through a simulation.
