论文摘要
本文描述了默奇森广场（Murchison Widefield Array）的使用，默奇森广场（Murchison Widefield Array）是一个低频的射电望远镜，在澳大利亚射电式望远镜上用作雷达接收器，构成了大陆跨度多型雷达网络的一部分，用于监视空间。本文详细介绍了所采用的系统几何形状，轨道特异性的雷达信号处理以及确保检测，跟踪和传播的居民空间对象所需的轨道测定算法。最后，该论文包括在全国各地的几个FM无线电发射机进行短暂收集活动之后处理的结果，最大基线距离超过2500公里。结果表明，默奇森广场阵列能够在低地球轨道中提供对物体的广阔场所和持续的覆盖范围。
This paper describes the use of the Murchison Widefield Array, a low-frequency radio telescope at a radio-quiet Western Australian site, as a radar receiver forming part of a continent-spanning multistatic radar network for the surveillance of space. This paper details the system geometry employed, the orbit-specific radar signal processing, and the orbit determination algorithms necessary to ensure resident space objects are detected, tracked, and propagated. Finally, the paper includes the results processed after a short collection campaign utilising several FM radio transmitters across the country, up to a maximum baseline distance of over 2500 km. The results demonstrate the Murchison Widefield Array is able to provide widefield and persistent coverage of objects in low Earth orbit.
