Radar Clutter Covariance Estimation: A Nonlinear Spectral Shrinkage Approach

Shashwat Jain, Vikram Krishnamurthy, Muralidhar Rangaswamy +2

In this paper, we exploit the spiked covariance structure of the clutter plus noise covariance matrix for radar signal processing. Using state-of-the-art techniques high dimensiona…
