<p>The method involves sandblasting an electromagnetic wave (11) of a radiation device (3) at a certain location (1). Incident wave components of the wave are received at another location (2) by two receiving devices (5,6). Another electromagnetic wave (12) is sandblasted at another radiation device at the former location. Incident wave components of the latter wave at the latter location, where the received signals are analyzed. Independent claims are also included for the following: (1) a system; and (2) two radiation devices for analysis of incident directions of waves.</p> |
