Abstract

In order to improve signal reception performance in GPS/INS/PL (Pseudolite) integration applications, a semi-sphere antenna array is proposed in this paper. It inherits the wide coverage characteristic of conventional spherical arrays and utilizes only about half the number of elements compared to a planar array to cover the upper-semi-sphere space above earth plane. It can process signals from both overhead and horizontal directions at the same time. Thus, unlike common planar arrays, this novel antenna array with a special geometry can receive satellite and Pseudolite (PL) signals from all directions, even from the horizon. Both Capon’s and constraint methods have been used in the simulations of Direction of Arrival (DOA) estimation and beamforming. These simulation results have demonstrated the advantages of the new array.
