Abstract

We consider a problem of detecting a random spatially distributed signal source by an array of sensors based on the generalized approach to signal processing in noise. We derive some generalized detector (GD) structures under several assumptions on the available statistics. The GD performance is evaluated and the effect of source angular spread is investigated. We notice the degrees of freedom of detection statistic distributions depend on both the signal angular spread and the number of data snapshots. At high signal-to-noise ratio and with small degrees of freedom, an increase of angular spread improves the detection performance. With large degrees of freedom the increase of angular spread reduces the detection performance. A comparison between GD and conventional beamformer is carried out by computer simulations. The results indicate a superiority of GD as the angular spread becomes large over the conventional beamformer detector.
