\"Techniques for predicting the maximum range of a detection radar are examined in a theoretical and practical introduction intended as a reference for scientists and engineers and as a textbook for short intensive courses in radar technology. Chapters are devoted to the radar range equations, signal detection, target cross sections, receiver noise, atmospheric effects, multipath propagation, clutter and interference, pulse-radar detection-range computations, and special types of radar.\"Fine condition (if ex-library) in cloth boards.
