摘要/Abstract

摘要：

针对基于二阶统计量的双基地多输入多输出雷达目标的波离方向和波达方向估计方法在冲击噪声环境下性能严重恶化，甚至失效的问题，提出了基于分数低阶矩Unitary ESPRIT的双基地多输入多输出雷达角度估计算法．首先从分数低阶统计量的基本定义出发，构造出分数低阶矩的矩阵，进而根据Unitary ESPRIT 算法的基本原理，实现了双基地多输入多输出雷达角度的正确估计，且估计参数可以自动配对．与传统的基于二阶统计量的Unitary ESPRIT算法和ESPRIT算法相比，所提算法能够有效地抑制冲击噪声，提高目标的角度估计性能．

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
