Estimation of the Cramer-Rao Bound for Radio Direction-Finding on the Azimuth and Elevation of Planar Antenna Arrays of the Symmetric Form

摘要

The paper deals with planar antenna arrays, such as circular, octagonal, hexagonal and rectangular, for the task of direction-finding on azimuth and elevation angles. The boundaries of the Cramer-Rao are calculated for different situations, including the location of signals in azimuth and elevation planes, and signal-to-noise ratios. Each antenna array consists of the same number of omni-directional antenna elements equal to 24, the distance between which is half the wavelength.
