An Array Diagnosis Method in the Presence of Array Mismatch and Impulsive Noise Environment

In this paper, an array diagnosis method in the presence of array mismatch and impulsive noise environment is proposed. In the case of array mismatch, there will be corresponding errors in array manifold of the array under test. In addition, taking into account the mixed noise present in the actual environment. Conventional array diagnosis methods based on compressive sensing cannot achieve the desired effect. In order to solve this problem, an array diagnosis method based on impulse noise environment is proposed with full consideration of array error. Based on the far-field data model of the antenna array, the mathematical model corresponding to the proposed problem is obtained. The l1-norm constraint is applied to the impulse noise. After derivation, a new optimization problem is obtained and solved. Finally, the proposed method is validated by computer simulation.
