低频阵列是一种基于相控阵原理的新型射电望远镜，工作频率为10-240 MHz。在灵敏度和分辨率方面的巨大改进超过了以前在这些频率下工作的仪器，加上相控阵方法（多波束，无移动部件）带来的更大灵活性，使LOFAR成为一种功能非常强大的新仪器。我们提出了一些科学的驱动程序，并给出了当前设计的概述。
The Low Frequency Array is a new radio telescope based on phased array principles that will operate at frequencies from 10–240 MHz. The vast improvement in sensitivity and resolution over previous instruments that have worked at these frequencies, together with the increased flexibility that results from the phased array approach (multi-beaming, no moving parts) make LOFAR an extremely versatile and powerful new instrument. We present some of the scientific drivers and give an overview of the current design.
