Description
These lectures are intended for Engineer graduates or Master Physics, who are interested in learning the basic techniques used in radio-astronomical observation and imaging. Efforts have been made to minimise the gap between the aimed science (radio-astronomy) and its instrument (radio-telescope) using complete engineering principles. These lectures are self comprehensible since sufficient explanatory-text has been added in the slides. For self-assessment, there are questions with hints for solution at the end of majority of the lectures.
Lecture-01: A superficial view of the above said techniques. It also includes the various coordinate systems required in radio-astronomy.
Lecture-02: Creates a theoretical background of antennae.
Lecture-03: Covers the fundamentals of a radio telescope.
Lecture-04: Gives a complete understanding of polarization analysis and its relation with radio-astronomical observation.
Lecture-05: Builds the basic concepts behind single-dish radio telescopes and phased arrays.
Lecture-06: Builds the basic concepts of radio-interferometer and arrays.
Lecture-07: Builds a very brief conceptual base of receiving systems used in radio astronomy.
Lecture-08: Explains how the aperture synthesis was developed and prepares a solid understanding of it.
Lecture-09: Explains the different methods used in radio-data processing along with calibration techniques.
Lecture-10: Explains the affects of propagating medium on radio signals and data.
Lecture-11: Gives a detailed description of the GMRT.
It is advised to go through the above lectures sequencially starting from Lecture-01 to Lecture-11. Lecture-01 may be skipped if the person has some understanding of radio-astronomy and various coordinate systems used in it. One may also skip slides in Lecture-01 except the coordinates, since the rest are available in the next lectures.
