An 8 GHz digital spectrometer for millimeter-wave astronomy
SPIE Proceedings, 2012We have designed and tested a digital spectrometer suitable for analyzing 8 GHz baseband signals. It is based on a 16- Gsps, 5-bit ADC from e2v and a Stratix-IV FPGA employed for later filtering and signal processing. Digitized data is received and synchronized via twenty high-speed 4-Gbps transceivers integrated in the FPGA.

Modern millimeter and submillimeter receiver systems for radio astronomy
Radiophysics and Quantum Electronics, 2009In this review we consider the composition and placement of receiver complexes on millimeter and submillimeter wave radio telescopes as well as their components and circuitry. Examples of receiver complexes are given for both ground-based and space radio telescopes.

Coherent Detector Arrays for Millimeter and Submillimeter Astronomy
2009Progress in many areas of astronomy requires large-area surveys and observations of extended objects. This includes the cosmic microwave background, nearby galaxies, the Milky Way, and regions of star-forming regions within our galaxy. The ability to carry out such studies is critically dependent on the development of affordable high-sensitivity focal ...

The Challenge of Astronomy to Millimeter-Wave Technology
IEEE Transactions on Microwave Theory and Techniques, 1976The inseparability of pure and applied science, or the synergy between scientific discovery and technological advance, has already been well illustrated in the field of radio astronomy. Recent astronomical discoveries in the millimeter range, and what can he expected to emerge from the far-infrared region, make further technological developments in ...

Millimeter Radio Astronomy and the Solar Convection Zone
PLANETARY RADIO EMISSIONS VII, 2011The global distribution of solar surface activity (active regions) is connected with processes in the convection zone. To extract the information on large-scale motions in the convection zone, we study the solar synoptic charts (Mount Wilson 1998-2004, Fe I, 525.02 nm). The clear indication of large-scale (= 18°) turbulence is found.

A Brief Overview of Millimeter-Wave Astronomy
1999Even in today’s specialized world, individual fields are so broad that they cannot be adequately represented within the limit of a few pages. Millimeter-wave astronomy is no exception. Nevertheless, I will attempt to give a reasonable overview of this rapidly-growing field within such a limit.

Millimeter radio astronomy and the genesis of ALMA
2015 IEEE MTT-S International Microwave Symposium, 2015Now nearing completion in northern Chile, the Atacama Large Millimeter/Submillimeter Array (ALMA) is a partnership between North America, Europe, East Asia, and the host country of Chile. ALMA is the first truly global radio astronomy project and arguably, the most complex ground-based astronomical instrument ever built. An imaging interferometer, ALMA

Recent Advances in Millimeter Wave Instrumentation for Radio Astronomy
1987 IEEE MTT-S International Microwave Symposium Digest, 1987During the past few years major advances have made in instrumentation for millimeter wave radio astronomy. Antennas have been built with large apertures and high precision and the sensitivity of receivers has improved greatly. This paper summarizes the more important of these advances.
