The development and application of random matrix theory in adaptive signal processing in the sample deficient regime
… the problem of regularization in the form of diagonal loading for two conventionally used spatial power spectrum estimators based on adaptive beamforming, and shows the asymptotic properties of the estimators, studies how the optimal diagonal loading behaves and compares the estimators on the …

Modal analysis of vertical array receptions for the Heard Island Feasibility Test
… was studied and improved upon through the use of diagonal loading. Lack of array orientation data hindered the analysis, and least squares fitting was used to estimate the most likely orientation. The least squares analysis indicated the presence of modes at least up to mode 7, possibly higher. …

Robust Implementations of the Multistage Wiener Filter
… concerns "soft stops", i.e., the insertion of diagonal loading into the MWF. Several methods for inserting loading into the MWF are described, as well as methods for choosing the amount of loading. The next area investigated is MWF rank selection. The MWF will outperform the classical Wiener …

Sensor Array Processing with Manifold Uncertainty
… gain for reduced rank adaptive processing with diagonal loading for snapshot deficient scenarios is analytically derived using asymptotic results from random matrix theory for a set ratio of sensors to snapshots. Additionally, the problem of near-field sources is considered and a method to …

Sparse spectrum fitting in array processing
… analysis in the first part of this thesis, Diagonal Loading technique is used to significantly reduce the sensitivity of SpSF with respect to its RP, which further enables the control of such sensitivity. Based on the Discrepancy Principle, an iterative version of SpSF, Iterative-SpSF …
