Geared toward undergraduates majoring in physics or astronomy, this textbook will accompany an undergraduate course on radio astronomy. Beginning with a basic motivation behind why conducting observations at radio frequencies is important, the text follows up with a review of essential physics concepts (corresponding to sophomore level physics it is assumed that the student has already completed two semesters of introductory calculus-based physics). Next, the author describes single dish telescopes with important quantities (such as system temperature, etc.) and provides a brief introduction...
