Abstract	This study focuses on the problem of deception jamming suppression for a radar system and an effective spatial-polarisational filter strategy is outlined based on the spatial and polarisational parameter joint estimates. It can make the false target filtered effectively and the desired target remained with an improved signal-to-jammer-noise ratio. In this scheme, the trilinear decomposition model is first employed to obtain paired 2D direction of arrive and polarisation parameter joint estimates of the target and jammer. Then a spatial-polarisational oblique projection filter operator based on the joint estimates is constructed and utilised to project the received mixed return of radar onto to the target echo sublinear space so as to suppress the jamming. Meanwhile, the complexity of the above jamming suppression algorithm is presented and the working flow of a radar system equipped with a polarisation sensitive array for countering the deception jammer is also presented. Simulation results demonstrate the performance of the proposed scheme.
