AST 0121164LonsdaleThe goals of this project are to produce a computer-model which will serve as a data simulator for a new type of radio telescope (a 400-km, low frequency, radio telescope that will work in the 10-240 MHz wavelength range). The output of this computer model will be used to study a variety of different instrument designs as well as develop techniques for the post-processing data analysis. The latter will include the development of a network architecture and protocol to support the data rates, support for dynamic range and fidelity levels that are beyond the present state-of-the-art, and the calibration of the ionospheric propagation delays and instrumental characteristics that require new techniques and algorithms. The project is part of the US participation in an international collaboration (designated LOFAR for Low Frequency Array) which is projected for operation in 2006. An additional $9-10 million is being invested in the design by Netherlands Foundation for Research in Astronomy (NFRA, [ASTRON in Dutch]) and the US Naval Research Laboratory (NRL). The National Academy of Sciences Decadal Survey of Astronomy (2001) recommended the project for NSF support. This effort is a major new astronomy initiative. NSF participation will guarantee wide access to the instrument by the US astronomical community, although the primary funding will come from NRL and ASTRON.***

该项目的AST 0121164 lonsdalethe目标是生产一种计算机模型，该计算机将作为新型射电望远镜的数据模拟器（400公里，低频，射电望远镜，该模拟器将在10-240 MHz波长范围内起作用）。 该计算机模型的输出将用于研究各种不同的仪器设计，并开发用于后处理数据分析的技术。 后者将包括开发网络体系结构和协议，以支持数据速率，对动态范围的支持以及超出当前最新时间的保真度，以及电离层传播延迟延迟和仪器特性的校准需要新技术和算法。该项目是美国参与国际合作（指定的低频阵列Lofar）的一部分，该合作计划于2006年进行运营。荷兰荷兰天文学研究基金会（NFRA，[荷兰的Astron In at Astron in Dutch]）和美国Naval Research Laboratory（NRL）向设计额外投资了9-1000万美元。 美国国家科学学院deTADAL ASTROMANTY（2001）建议该项目进行NSF支持。 这项工作是一项主要的新天文学倡议。 NSF的参与将确保美国天文学界广泛访问该工具，尽管主要资金将来自NRL和Astron。***
