Abstract :
The fourth order cumulants have been shown to increase the effective aperture of an antenna compared to second order cumulants. In this paper, we investigate the potential benefits of fourth order array processing methods for the direction of arrival estimation of GPS satellites. The purpose of this paper is to present the results obtained from real measurement data. The measurements have been carried out using our 7-element planar GPS antenna (L1-Band) and our 8-channel real-time recording system.
