Equivalence of adaptive array diagonal loading and omnidirectional jamming

IEEE Transactions on Antennas and Propagation, 1995
Diagonal loading, where a diagonal matrix is added to the estimate of the covariance matrix, is often used in adaptive arrays to minimize the array's responsiveness to random fluctuations in the estimate of the interference environment. Poor estimates of the covariance matrix often result in high random sidelobes in the sample matrix inversion (SMI ...

Fast and Robust GSC Beamformer based on Variable Diagonal Loading

2006 CIE International Conference on Radar, 2006
In this paper, a fast and Robust GSC beamforming algorithm based on variable diagonal loading is proposed using Multistage Wiener filter techniques. Firstly, the loading level can be accurately determined through MSWF decomposition. In conjunction with match filter loading method, the efficient technique achieves the advantages of robust capabilities ...

Investigation on improved water-loaded diagonal horn applicators for hyperthermia

Journal of Electromagnetic Waves and Applications, 2016
AbstractThis paper describes simulation, theoretical, and/or experimental studies of specific absorption rate (SAR) distribution in biological phantom (muscle)/tri-layered bio-media without and with irregular-shaped tumors in direct contact with improved water-loaded metal diagonal horns designed at 2450 and 915 MHz. Further, thermal simulation results

Adaptive detection with diagonal loading (for adaptive antenna array)

International Conference on Acoustics, Speech, and Signal Processing, 2002
An adaptive detector with diagonal loading is presented, and although it is not CFAR (constant false alarm rate), it is conjectured that its probability of false alarm can at least be upper bounded by choosing the appropriate threshold for the adaptive matched filter detector.

On universal diagonally loaded beamformer under steering vector mismatch

The Journal of the Acoustical Society of America
We explore universal adaptive beamforming (UABF) under the non-ideal conditions of steering vector mismatch and signal contamination of data. We focus on the optimal choice of diagonal loading level as the regularization parameter. Assuming a statistical characterization for the steering vector mismatch, we use the average output signal-to-interference
