Second order methods in signal processing for spatial analysis are limited by the correlation between sources . In fact, the sources must emit independent signais in order to satisfy the exigences of theses methods as well as to obtain high resolution. The method proposed here, increases the rank of the matrix that contains the vectors used ta reform the source sub-space basis . This is like a source decorrelation. The advantage of this new method is that it continues to separate with a high resolution sources that are totally correlated unlike the popular method of spatial smoothing . This article shows how the DEESE algorithm use translational invariance and directional invariance of the linear arrays for the recuperation of an ...
