一、前言近廿年来,由于雷达、声纳和地震学中所出现的许多实际问题,大大推动了阵处理领域研究的蓬勃开展。本文不是一篇全面综述,不想对各种流派及有助于了解阵理论的各种高等数学分析不偏不倚地一一予以介绍。笔者感到,阵处理目前已是一个很成熟的领域,许多相当简单的直觉的概念都可以由正式的研究论文中概括出来。我们要提到的这些直觉的概念是这样一类简单的问题:我们学到了什么以及为什么这些结论是可信的?至于那些正统的证明目前文章很多,有兴趣的读者可以参阅之。
I. INTRODUCTION In the past 20 years, due to many practical problems in radar, sonar and seismology, the research in array processing has been greatly promoted. This article is not an exhaustive overview, and does not want to give an unbiased introduction to the various genres and various advanced mathematical analyzes that contribute to the theory of the matrix. The author feels that array processing is now a very mature field and that many fairly straightforward notions of intuition can be summarized in formal research papers. The notion of intuition we are talking about is a simple question: what have we learned and why are these conclusions credible? As for the orthodox proofs, there are many articles available to interested readers.
