A Statistical Framework for Optimizing and Evaluating MRI of T1 and T2 Relaxometry Approaches
Yang Liu, John R. Buck, Shaokuan Zheng
This paper proposes a statistical framework to optimize and evaluate the MR parameter and mapping capabilities for quantitative MRI relaxometry approaches. This analysi…
Wideband Source Enumeration Using Sparse Array Periodogram Averaging in Low Snapshot Scenarios
Yang Liu, John R. Buck
This paper proposes a new sparse array source enumeration algorithm for underdetermined scenarios with more sources than sensors. The proposed algorithm decomposes the wideband sig…
Broadband Sparse Array Focusing Via Spatial Periodogram Averaging and Correlation Resampling
Yang Liu, John R. Buck
This paper proposes two coherent broadband focusing algorithms for spatial correlation estimation using sparse linear arrays. Both algorithms decompose the time-domain array data i…
An Experimental Evaluation of the Generalized Sinusoidal Frequency Modulated Waveform for Active Sonar Systems
David A. Hague, John R. Buck
This paper experimentally evaluates the Generalized Sinusoidal Frequency Modulated (GSFM) waveform, a generalization of the Sinusoidal Frequency Modulated (SFM) waveform. The Insta…
Random Matrix Theory Model for Mean Notch Depth of the Diagonally Loaded MVDR Beamformer for a Single Interferer Case
Saurav R Tuladhar, John R Buck, Kathleen E Wage
Adaptive beamformers (ABFs) suppress interferers by placing a notch in the beampattern at the interferer direction. This suppres- sion improves detection of a weaker signals in the…
Unit circle rectification of the MVDR beamformer
Saurav R Tuladhar, John R Buck
The sample matrix inversion (SMI) beamformer implements Capon's minimum variance distortionless (MVDR) beamforming using the sample covariance matrix (SCM). In a snapshot limited e…
