Matched and Mismatched Estimation of Kronecker Product of Linearly Structured Scatter Matrices Under Elliptical Distributions

The estimation of covariance matrices is a core problem in many modern adaptive signal processing applications. For matrix-and array-valued data, e.g., MIMO communication, EEG/MEG (time versus channel), the covariance matrix of vectorized data may…

Off-Grid Radar Target Detection with the Normalized Matched Filter: A Monopulse-Based Detection Scheme

In this paper, we tackle the problem of off-grid radar target detection based on the Normalized Matched Filter. State-ofthe-art solutions to this problem include the use of the Generalized Likelihood Ratio test (GLRT), whose implementation can be…

Efficient Estimation of Kronecker Product of Linear Structured Scatter Matrices under t-distribution

This paper addresses structured scatter matrix estimation within the non convex set of Kronecker product structure. The latter model usually involves two matrices, which can be themselves linearly constrained, and arises in many applications, such…
