Abstract :
A solution is presented to the general multiple-source location problem with the sources being either incoherent, partially coherent, or coherent narrowband plane waves contaminated by unknown noise at the sensor terminal. The method provides the required source azimuth-elevation angle estimates, and the array´s geometry is diversified. Comments are given on linear array properties. An example of direction finding operating on a spatial series is included
