摘要：

Direction finding techniques are usually based on the second-order statistics of the received data. In this paper we derive two types of direction finding algorithms which use the fourth-order cumulants of the array data. One is a MUSIC-like technique based on eigendecomposition of a suitably defined cumulant matrix. The other is an optimal (minimum variance) estimator based on minimization of a certain cost function. The algorithms are derived and their performance is illustrated by numerical examples. Formulas are derived for the asymptotic performance of the optimal algorithm.
