Abstract : The question of what limitations the atmosphere may impose on the useful bandwidth for line-ofsight propagation in the centimetric-millimetric wavelength region was investigated. However, no explicit solution was obtained. The concepts fundamental to the general problem, with specific attention to the line-of-sight case, are discussed. One basic problem is the definition ofA REALLY SUITABLE, UNIQUE PARAMETER TO BE TAKEN AS THE BANDWIDTH OF A TIME-VARYING SYSTEM. Also, it is concluded that neither the single-scatter results nor the existing theories based on a multiple-scatter mechanism furnish an adequate base f r performing bandwidth calculations. (Author)
