Azimuth and elevation angle estimation with a three-dimensional array

This correspondence provides expressions for the Cramer-Rao lower bounds for the estimates of azimuth and elevation made with an arbitrary three-dimensional array of sensors. These results are formulated for a plane wave Gaussian signal in uncorrelated Gaussian noise. In addition, sufficient conditi...

Description
Summary:	This correspondence provides expressions for the Cramer-Rao lower bounds for the estimates of azimuth and elevation made with an arbitrary three-dimensional array of sensors. These results are formulated for a plane wave Gaussian signal in uncorrelated Gaussian noise. In addition, sufficient conditions on the array geometry are given which ensure that the azimuth and elevation angle estimates are uncoupled.< >
