Circular parabolic antennas play an important role in cutting-edge scientific fields such as space, astronomy, and telecommunications, as well as being commonly seen in household satellite broadcast reception antennas.
This book aims for readers to "learn the principles of parabolic antennas by doing," rather than just vaguely understanding them. This is likely a method of understanding that antenna experts would not typically employ. Since the approach is to "take a bite," the goal is to understand through experience rather than just intellectually, without using complex mathematical formulas.
The book also explains the "ALMA Project," which combines a total of 66 giant parabolic antennas, 12m and 7m in diameter, built in Chile, to observe celestial bodies with short-wavelength radio waves. It also provides a detailed introduction to VLBI (Very Long Baseline Interferometry), an observation technique that achieves ultra-high resolution equivalent to a "giant Earth-sized telescope" by simultaneously receiving radio waves from celestial bodies with multiple radio telescopes thousands of kilometers apart and synthesizing the data.
