Abstract

The most important thing in millimeter and sub-millimeter wave VLBI is how to calibrate the variations in the phase of an electromagnetic wave propagating through the troposphere. A lot of techniques for calibrating the phase fluctuations due to troposphere have been well proposed and demonstrated [1],[2],[3]. The millimeter wave multi-channel receivers system which can be used for phase calibration in millimeter and sub-millimeter wave VLBI observation are proposed. In this paper, a conceptual multi-channel receiver system and a quasi-optical filters which could be used in this receiver are described.
