This report describes the research to investigate algorithms for locating simultaneously multiple signal sourcesjammers using linear antenna arrays and digital signal processing. Specifically, the signals impinging on each of the antenna elements are converted to base band and digitized. The digital samples from all the antenna elements are fed to a computer which carries out direction finding, and later beam forming and signal extraction. The problem of multiple signal source location with a linear array is formulated. Once this problem is solved, it is a simple matter to extend to the case where two mutually perpendicular linear arrays are used to determine azimuth and elevation angles of signal sources.
