Multi-mainlobe Interferences Suppression Based on Interference Covariance Matrix Reconstruction
Shuai Pan, Yongshun Zhang, Qichao Ge, Renrong Hu, Chong Jing Yan · Journal of Physics Conference Series · 2019
Here a novel eigen-projection matrix preprocessing (EMP ) technology in view of covariance matrix rebuilding is presented. The eigenvectors of multiple mainlobe interferences are calculated via the correlation of eigenvectors between the sample covariance matrix ( SCM ) and this reconstructed mainlobe interference-plus-noise covariance matrix (IPNCM). Simulation consequents exhibit the excellence of this presented technique over this normal EMP method.
