Abstract :
Evaluation tests are carried out on the direction finder, which has an aperture comprising four monopoles on the circumference of 0.4 λ. Radial bias function (RBF) neural network and a new post-processing procedure are used in the algorithm of DOA estimation. The estimation error was reduced to one-tenth that of MUSIC.
