Experimental probing of multipath microwave channels


  • M. Sylvain


It is very difficult to relate the behavior of a multipath microwave channel to its physical description. Much information, however, can be gained from radioelectrical probing of the channel, and models can be built independent of the complex underlying physical situation. In this paper we review the various experimental techniques used to investigate the channel, their successes, and their limitations. We conclude by stressing the directions in which progress has to be made.
