Abstract :
Direction finding of radio activities using an arbitrary array conformed to a spherical surface is described. It is based on a transformation of the signal of the arbitrary array into a uniform linear virtual one. In this form, a selected direction finding estimator can be applied in the environment of incoherent/coherent sources
