An adaptive error correction method for array receiver

Abstract

In order to avoid the influence of amplitude-phase error and delay difference between the receiving array elements, an adaptive array error correction method combining STAP structure and SV-LMS algorithm is introduced in this paper. The SV-LMS algorithm is used to calculate the amplitude and phase errors of the arrays, and then the STAP structure is used to calculate the time delay. The amplitude and phase errors and time delay of the arrays can be obtained adaptively. Finally, the effectiveness and feasibility of the algorithm are verified by simulation.
