Novel detection model for MIMO radar in multipath environment

In this paper, a novel detection model for Multiple Input Multiple Output (MIMO) radar based on entropy theory in multipath environment is discussed. The proposed model, which defines the concept of Multipath Distance Difference (MDD) in depth, studies the variance and correlation of multipath scattering coefficient with MDD systematically according to the multipath received signal model. We illustrate that our model can use the multipath echo power to improve the detection performance by introducing the uncertainty analysis into the model. The simulation results demonstrate that the proposed method can achieve performance improvement due to the realistic physical model.
