A New Method of Joint Bearing-Elevation-Range Estimation of Near Field Sources

摘要

The three-dimensional parameter (bearing, elevation and range) estimations of near-field sources are discussed in this paper. Based on a cross-array, a new method for bearing-elevation-range estimation by using array geometries and exploiting signal space-domain and time-domain' information in near field is presented. The method utilizes array aperture fully and can estimate more sources' parameters. It also has the merits of the good resolving power and no needing spectral peak search. Its effectiveness is illustrated by the simulation results.
