4th international Symposium on Independent Component Analysis and Blind Signal Separation(ICA2003), April 2003, Nara, Japan HOS Criteria \& ICA Algorithms Applied to Radar Detection M. BOUZAIEN and A. MANSOUR E3I2, ENSIETA, 29806 Brest cedex 09, (FRANCE). ABSTRACT This paper deals with radar detection and identification problems. Nowadays, To improve radar detection capability, engineers use high resolution methods (i.e. ESPRIT or MUSIC {etc}). Recently, some methods based on High Order Statistics (HOS) have been used for the same purpose. Here, a comparaison among different methods is proposed. In addition, the application of ICA algorithms in this field is discussed.} KEY WORDS: BSS, ICA, MUSIC, ARMA, ESPRIT, High Resolution Methods, Crosstalk, SNR, Real World Applications.
