Abstract

Process for estimating the correlation matrix of signals of unknown characteristics in an array of N sensor. The process determines the correlation matrix Rs of the signals of known characteristics, estimates the correlation matrix Rx of the sensor signals, forms a matrix A equal to A=Rs<-1/2>Rx Rs<-1/2 >and decomposes the matrix A into eigenelements, constructs a matrix B based on the eigenelements of the matrix A, and determines the estimated correlation matrix Rb of the interfering signals based on the estimated matrix Rs and of the matrix B, such that Rb=Rs<1/2 >B Rs<1/2>. Such a process may find application to antenna processing.
