Phased array failure detection and correction by Yeo, Beng Kiong.

“…This Ph.D. thesis is focused on the element failure detection of high frequency surface wave radars (HFSWR) using analog beamformer, and the failure correction techniques for adaptive digital beamforming arrays. By the end of our research, we have developed an SVM-based method for HFSWR failure detection, and an iterative convex optimitization (ICO) technique for the failure correction of uniform linear arrays (ULA) and planar arrays with digital beamforming. …”
