An improved hybrid interferometer

Abstract

In this paper, three alternatives to AOA determination are considered: the hybrid interferometer using MUSIC resolution, the hybrid interferometer using the comparison approach to resolution and the hybrid-MUSIC approach. It is seen that the hybrid interferometer (MUSIC) is more accurate than the hybrid interferometer (comparison). On the other hand, hybrid interferometer (MUSIC) is not as accurate as the hybrid-MUSIC, but does not require excessive computational resources to achieve AOA estimates whose bias and standard deviations are much improved over other hybrid approaches as well as the linear phase interferometer.
