Aiming at the problem of jamming suppression in distributed radars, a joint polarization-spatial-temporal domain processing method is proposed for compound jamming in distributed radars. Firstly, a distributed polarization array radar system model of single-transmitter multiple-receiver is established. Secondly, the received signal is reconstructed into a third-order tensor according to its polarization-spatial-temporal characteristics. Furthermore, tensor decomposition is employed to separate the target echo from jamming signals, so as to realize the suppression of blanket jamming and smart jamming. Then, by using the uniqueness of the position and velocity information of the real target, the deception jamming is suppressed by joint positioning of multiple sites, while the position coordinates and velocity vectors of the target are estimated in the meantime. Finally, the effectiveness of the proposed algorithm is verified by numerical simulation experiments.
