Azimuth and elevation estimation for noncircular signals
J. Liu, Zhiping Huang, Yiyu Zhou · Electronics Letters · 2007
A novel 2D direction-finding algorithm for noncircular signals using two parallel linear arrays, called the extended rank reduction (ERARE) algorithm, is presented. The method needs only 1D search for joint azimuth and elevation estimation. The azimuth and elevation angles estimated by ERARE are paired automatically.
