| Abstract: |
We consider the problem of source number estimation in the presenceof unknown spatially nonuniform noise. Successive array element suppression is applied to isolate the contribution of the noise powers and a likelihood function is derived. When it is combined with the appropriately defined penalty function, an MDL-like criterion is defined. Performance of the new criterion is assessed through simulations and it is shown that the method is powerful in a nonuniform noise environment. |
