一、引言在文献[1,2]中研究了传感器阵的最佳处理的理论。在理论上给出了检测空间信号的最佳结构。鉴于实现这种最佳结构的复杂性,一个合理的问题是,“在实际上实现这种众所周知的最佳阵处理器的次最佳结构是什么?”考虑任何其正的最佳系统时,从设计工程师的角度来看,由于设备和经济的限制,这个问题是很自然的。因此本文的目的是指出:(1)在许多情况下,一类次最佳(即次于完全自适应)的自适应系统能够给出接近最佳的阵性能,同时设备要求合理。(2)对一特定的基阵,次最佳自适应阵的控制运算法,应根据信号与干扰环境的情况 I. INTRODUCTION The theory of optimal processing of sensor arrays has been studied in the literature [1,2]. In theory, the best structure of signal detection space is given. Given the complexity of implementing this optimal structure, it is reasonable to ask, “What is the next best structure for actually implementing this well-known, best-in-class processor?” "Consider any positive optimal system From a design engineer’s point of view, this is a natural problem due to equipment and economic constraints. Therefore, the purpose of this paper is to point out: (1) In many cases, a suboptimal (ie, sub-fully adaptive) adaptive system can provide near-optimal array performance with reasonable device requirements. (2) For a particular array, suboptimal adaptive array control algorithm, should be based on the signal and interference environment conditions
