Real time wideband direction finding
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015 In this paper, the developed FFT based interferometric direction finding of wideband radar threats for electronic support (ES) and electronic intelligence (ELINT) is presented. Using this method, target radar signal is separated from other radar signals using FFT. Phases of extracted radar signals for two or more channels are calculated.

Finding Sparser Directed Spanners.
, 2010 A spanner of a graph is a sparse subgraph that approximately preserves distances in the original graph. More precisely, a subgraph $H = (V,E_H)$ is a $k$-spanner of a graph $G=(V,E)$ if for every pair of vertices $u,v \in V$, the shortest path distance $dist_H(u,v)$ from $u$ to $v$ in $H$ is at most $k.dist_G(u,v)$.

Direction Finding Using GHA Neural Networks
Al-Khawarizmi Engineering Journal, 2017 This paper adapted the neural network for the estimating of the direction of arrival (DOA). It uses an unsupervised adaptive neural network with GHA algorithm to extract the principal components that in turn, are used by Capon method to estimate the DOA,
