Abstract

Abstract:

A fractional lower order moment unitary ESPRIT (FLOM-Unitary ESPRIT) for the joint direction of departure (DOD) and the direction of arrival (DOA) estimation in bistatic multiple input multiple output (MIMO) radar is proposed, which combates the problem of algorithms based on second-order statistics performance declining considerably in impulsive noise environments. Firstly, the fractional lower order moment matrix is constructed based on the basic definition of fractional lower order statistic. Moreover, according to the basic principle of the unitary ESPRIT algorithm, the angle estimation could be performed correctly and paired automatically. Compared with the unitary ESPRIT and ESPRIT algorithms, the proposed algorithm effectively suppresses impulsive noise and the angle estimation performance is improved. Several numerical results verify the effectiveness of the proposed algorithm.

Key words: bistatic multiple input multiple output radar, fractional lower order moment, direction of departure, direction of arrival, Unitary ESPRIT
