Embodiment 1

[0010] Embodiment 1: refer to figure 1 , figure 2 , image 3 : The POST antenna adopts a double off-axis card-focus system plus a Kud focus design. The structure of the antenna is as follows. The antenna is composed of two mirrors, the primary mirror is parabolic, and the secondary mirror is hyperbolic. These two mirrors are confocal, and the common focus is used as the origin of the coordinates. The two mirrors are staggered in the x-axis direction without overlapping, which is the most commonly used off-axis structure; b. The axes of the two mirrors are staggered in the z-axis direction, with an included angle β; this style The off-axis is unique to this design; the so-called "Court-style focus" is generally used in optical telescope systems, and refers to a technique of folding light. Since the propagation of electric waves has the property of light propagation when the frequency is high, in the design of this telescope, when the electric waves are reflected from the se...

Abstract

A mobile submillimeter-wave telescope is composed of antenna, signal receiving system, control system and signal processing system. It features its off-axis Cassegrin antenna, small GPS receiver and modular design.

Description

technical field [0001] The invention relates to a radio astronomical telescope, in particular to a mobile submillimeter wave telescope. Background technique [0002] Radio astronomy telescope is the main research tool of radio astronomy, mainly composed of antenna, signal receiving system, control system and signal processing system. The frequency range of its work is generally in the millimeter wave band or the submillimeter wave band. Submillimeter-wave telescopes covering the frequency range of 492 GHz are commonly used internationally, and there are quite a lot of literature reporting on them. But radio telescopes with such a high frequency have not yet been developed in China. Radio telescopes at home and abroad are all fixed at one location and cannot be moved frequently. And many tasks, such as the site selection of the observatory, need to be equipped with a movable submillimeter wave telescope working at 492 GHz, which requires the volume and weight of the origin...
