In order to solve the requirement of Space-Time Adaptive Processing (STAP) for a sufficient number of stationary training snapshots. In this paper, a new method, named as Tensor Sub-beam Synthesis-STAP (TSS-STAP), for designing STAP tensor beamformer is proposed. Analysis shows that the tensor beamformer required in STAP can be synthesized by the tensor outer product operation of the sub-beamformers, where each of the sub-beamfomer is designed in the each sub-dimension of a tensor, since the proposed beamformer is designed in the sub-dimension of a tensor which has lower Degrees of Freedom (DoF), so that the required training snapshots and computational complexity are reduced. Moreover, it is also shows that the proposed beamformer can effectively do decorrelation processing, so that a better target detection performance in non-uniform clutter environment is obtained. Simulation results show that the proposed method effectively improves the target detection result and reduces the time consumed by the target detection.
