Abstract :
This paper presents direction-finding techniques for smart antennas based on conformal and irregular antenna arrays. Methods of spectral estimation are considered to estimate directions-of-arrival (azimuth and elevation) using two-dimensional arrays and three-dimensional arrays (conformal arrays). The effects of arbitrary arrays on the performance and on the resolution of direction-finding algorithms are illustrated by simulation results.
