Abstract :
Two types of high-resolution direction-finding algorithms which use the fourth-order cumulants of the array data are derived. One is a MUSIC-like technique based on eigendecomposition of a suitably defined cumulant matrix. The other is an optimal (asymptotically minimum variance) estimator based on minimization of a certain cost function
