摘要

The present issue (vol.82, no.2, 1994) is the third in the Proceedings of the IEEE to be devoted to radio and radar astronomy. The first appeared in January 1958, a significant date because it was 25 years after Karl G. Jansky's first report of his discovery of Galactic radio noise. The second was 15 years later in September 1973, and was devoted to reporting how the science had progressed. The 15-year timespan had marked a period of rapid advance that had yielded a wealth of discoveries. Now, 21 years later, the field is still dynamic and continues to produce an abundance of findings, due in part to the large number of new observatories. In the present issue, the focus is on the design and performance of the antennas and the instrumentation used in radio astronomy. The issue concentrates on already existing and operational telescopes. Perhaps yet a future issue is merited, one devoted to those new telescopes that are still on the drawing boards.

Jansky)首次发现银河系无线电噪声的报告已经25年了。第二个是15年后的1973年9月,它致力于报道科学的发展情况。 15年的时间跨度标志着一段飞速发展的时期,这产生了许多发现。 21年后的今天,该领域仍然是动态的,并继续产生大量的发现,部分原因是有大量新的天文台。在本期中,重点是射电天文学中使用的天线和仪器的设计和性能。问题集中在已经存在和正在使用的望远镜上。也许还值得考虑一个未来的问题,那就是专门针对那些仍在绘图板上的新型望远镜。
