Terrain Profiles and Contours in Electromagnetic Wave Propagation.
Abstract
The Meeting explored propagation problems associated with terrain profiles and contours. Specifically examined were theoretical aspects, methods of digital terrain mapping, and terrain effects on antenna characteristics. Future communication and data transmission will make extensive use of digital terrain maps. Characteristics of terrain near terminals or communication links may provide protection against interference from other sources. Experimental data interpretation requires understanding of sensors and antennas. Theoretical contributions include cw and transient scattering from statistically rough and smoothly varying terrain. Analytical methods include full wave solutions, ray techniques, and modal techniques. The program of the Meeting consisted of five sessions covering the following main topics: (1) Terrain effects on antenna characteristics; (2) Propagation effects in terrain mapping; (3) Theoretical aspects of scattering and emission from terrain; (4) Methods of digital terrain mapping; (5) Measurement of terrain parameters. A round table discussion was concerned with the current and future trends in the areas covered by the above sessions. (Author)
