A clutter suppression method based on the intrinsic mode functions reconstruction and information geometry space detection

In this paper, we applied a clutter suppression method based on the complex empirical mode decomposition (CEMD), which by screening the intrinsic mode functions (IMFs) to reconstruct signal for clutter suppression. The data before and after clutter suppression is processed using the information geometry method and calculating the geometry distance between center cell with the neighboring cell. Simulation results verified that by comparing the information geometry before clutter suppression, the number of false targets and false alarm probability reduce by combining CEMD and information geometry method in the clutter background. And the detection probability is improved effectively after clutter suppression with CEMD.
