摘要

本文的目的是讨论阵列诊断中的环境滤波技术。其基本思想是利用差分测量技术,以稀疏度为判别标准,区分阵列贡献和干涉场。基本上,通过混合最小1范数和迹范数最小化,将与故障单元相关的场与干扰源辐射的场分开。数值算例表明了该技术的潜力。

An investigation on an interference filtering technique for array diagnosis using sparsity
The aim of this contribution is to discuss an environmental filtering technique in array diagnosis. The basic idea is to distinguish the array contribution from the interference field using sparsity as discriminant by means of differential measurement technique. Basically, the field associated to the fault elements is separated by the field radiated by interference source using a mixed minimum ℓ1 norm and trace norm minimization. Numerical examples show the potential of the technique.
