Abstract

The first phase of the MeerKAT radio telescope [4] has been installed on the Karoo site. This phase includes all 64 antennas fitted with L-band receivers and digitizers, signal and data transfer systems, time and frequency reference, the correlator/beamformer hardware, control software, and science data processing hardware and software, Not all of the functionality required to execute the eight large scale projects (LSPs) that have been prioritized is available at the moment, but commissioning and test observations have been conducted using the L-band receivers and the first correlater/beamformer firmware releases. Test images of the Galactic Centre, the Galactic Plane and deep extragalactic fields indicate that all of the telescope subsystems are functioning correctly, and specifically that the analog and digital signal paths (including the dish optics) are operating operating within specification. The sensitivity of the L-band instrument is twice that initially specified in the call for large survey projects [1].

MeerKAT射电望远镜的第一阶段[4]已经安装在卡鲁站点上。这一阶段包括所有64个天线,配备l波段接收器和数字化仪、信号和数据传输系统、时间和频率参考、相关器/波束形成器硬件、控制软件和科学数据处理硬件和软件。目前,执行8个优先考虑的大型项目(LSPs)所需的所有功能都是可用的。但是已经使用l波段接收器和第一个相关器/波束形成器固件版本进行了调试和测试观察。银河中心、银河面和深河外场的测试图像表明,所有望远镜子系统都正常运行,特别是模拟和数字信号路径(包括碟形光学)都在规范范围内运行。l波段仪器的灵敏度是最初在大型调查项目呼吁中规定的两倍[1]。
