Abstract :
One of the recently proposed preprocessing approaches to decorrelate coherent signals is the spatial filtering method which includes the spatial smoothing algorithm as one of its particular cases. The spatial filtering (SF) algorithm is based on the design of several FIR spatial filters which are aimed at effectively decorrelating coherent signals. The authors study and analyze the SF algorithm and then elaborate more on its statistical analysis under different conditions.<>
