摘要
为了实现对短波频段全空域低信噪比信号的良好接收 ,本文提出了一种窄波束全向接收的自适应天线阵。文中首先简要回顾了自适应天线阵的基本理论 ,并针对短波波段频程较宽的特点 ,提出了一种接收信号频率决定阵元间距的阵元间距动态可变组阵方案 ,文末通过计算机仿真比较了该方案实现的窄波束全向接收自适应天线阵和常规短波天线阵的性能。
In order to receive omnidirectional low-SNR signal of whole HF band, we present an adaptive omni-direction & narrow-beam receiving antenna array. In this paper, the basic theory of adaptive antenna array is firstly reviewed, and then a scheme of dynamic space between array elements determined by receiving signal frequency is developed. The performance comparison between the adaptive omni-direction & narrow-beam receiving antenna array and conventional antenna array is shown by computer simulation in the end of this paper.
