Spatial structure optimization for a signal source tracking system under influence of interfering signals

Directional antennas are used for improving the throughput of unmanned vehicle data transition system. Synthesis and analysis of algorithms for estimating the direction to the signal source under the influence of spatially correlated interfering signals in two-dimensional few-element antenna array have been carried out for deterministic, quasideterministic, Gaussian signal. The analytical expressions for the lower bound of the variance of the estimation error for angular coordinates have been obtained. The parameters of dispersion ellipses for estimated angular coordinates have been calculated. The influence of the spatial structure on the error in determining the direction to the signal source is being investigated.
