Abstract :
The necessary and sufficient conditions in terms of antenna array geometry for unique estimation of azimuth-elevation-carriers (AEC) of narrow-band signals are introduced. These conditions make it possible to solve the problem of joint AEC estimation based on spatial samples taken by the volume array without using a large number of temporal samples.
