The Study On Localization Technology Of Signals Based On The Improved Circular Array

The research of exact signal estimation techniques is an important research field inmodern signal processing. This begins at the array model and put the emphasis onresearches of direction-of-arrival estimation algorithms. At first the classicaldirection-finding algorithms in array signal processing are introduced, some of them aresimulated. After that with comparation of front space smooth algorithm, Using front-rearspace smooth algorithm, save the quantity of computation. Aperture extension algorithmby cumulants by which, emphatically researched for direction-fording.
