High Dimension Space Time Adaptive Processing Based on FFT

One of the advantages of the joint space time adaptive processing technique is that the freedom degree can be increased greatly without adding any antenna elements, which can improve the ability of the anti-jamming array to reject the narrow band jamming. But the disadvantage is that the computation will be more and more complex with the processing dimension being higher and higher. In this paper, a fast implementation method for high dimension space time adaptive processing is proposed based on both matrix Teoplitz feature and MSNWF. The new method provides a realization solution for high dimension space time adaptive processing. The anti-jamming convergence simulation experiment result shows that this new implementation method is feasible and efficient.
