Jian Yang, Liu Rui-qi, Xi Xu-qi · 2016
Under the condition of low sample, how to improve the robustness of adaptive beamforming algorithm is a key problem in engineering application. This article first introduces the minimum variance distrtionless response. On the basis, the algorithm of diagonal loading has been researched and how to select the optimal loading value in the practical application has been emphatically analyzed. Finally, the simulation based on certain array receiving system has verified the correctness of the algorithm.
