Abstract:

The purpose of the Tropical Propagation Research Project is to investigate radio wave propagation in tropical environments. Its research is conducted through field measurement programs in Thailand that are followed up by mathematical analyses in the United States. This semiannual report describes recent experimental results from the projects second phase of tests. A section of heavy rain forest, identified as Area II in Figure 1.1, is the setting for the present tests. Begun in 1966, the second test phase is providing data to refine and expand conclusions drawn from an initial series of propagation tests. The initial phase of research, lasting from 1962 to 1966, was conducted in a region of medium heavy jungle, Area I in Figure 1.1. The two other test locations, Areas A and B, that appear in Figure 1.1 are part of the initial research phase and consist of small plots of jungle used for short-range tests with frequencies at 550 Mcs and above. Area A lies within Area I, and Area B was a section of bamboo growth on the sea coast.
