HIGH-FREQUENCY CUTOFF IN TYPE III BURSTS
In this article we report about a group of solar bursts with high-frequency cutoff, observed on 19 August of 2012 near 8:23 UT, simultaneously by three different radio telescopes: the Ukrainian decameter radio telescope (8-33 MHz), the French Nançay ...

The Measurement of Polarization in Radio Astronomy [PDF]
Modern dual-polarization receivers allow a radio telescope to characterize the full polarization state of incoming insterstellar radio waves. Many astronomers incorrectly consider a polarimeter to be the "backend" of the telescope.

A Design Study of 100GHz Band Local Oscillator System by Using Yig Oscillator [PDF]
In this paper, we make a design study for a local oscillator system of the 100 GHz band cosmic radio receiving system. We use the YIG oscillator with digital driver which is the main oscillator. This oscillator has a good frequency and phase stability at
