Radio Telescope Design

Part of the Astrophysics and Space Science Library book series (ASSL,volume 360)

This is an important chapter concerning radio telescope design. In the first part of this chapter, all the major design issues of radio telescopes are discussed, which include the reflector surface transmission loss, the antenna tolerance theory, the antenna homology design, the antenna surface best fitting, the antenna component positional tolerance, the antenna aperture blockage, the ground radiation pick-up, and antenna best fitting through ray tracing. Theories and formulas are provided so that the readers will have a full understanding of antenna design requirements and they can apply these theories and formulas to their design project. In the second part, different types of radio antenna structure, wind loading on antennas, and active radio telescope structure control are discussed. An overview of typical steerable paraboloidal antenna backup structure design is provided. The active control of a radio telescope involves secondary mirror position control and primary mirror surface control. These control systems are all used only in a few antennas at present. In the last part of the chapter, theory and realization of radio interferometers is discussed together with a number of existing large interferometers. The data calibration in radio interferometers is also discussed so that readers can easily get into this most difficult radio observation field.
