<p>PROBLEM TO BE SOLVED: To provide a rotational radio beam rotation device by that which the energy loss of a radio beam is eliminated, and to provide the application device. SOLUTION: A radio beam rotation device reflects a transmission/reception beam transmitted/received by a transmission/reception port 1 only at one reflection face 4 and directs a prescribed radio beam 5 in a prescribed direction so as to rotate it. The transmission/reception beam 2 is transmitted/received in a constant direction (a) by the transmission/reception port 1. The reflection face 4 is arranged at an angleθ, which obliquely crosses the constant direction (a). An arm 6 which is arranged on a side opposite to the direction of the radio beam 5, with respect to the transmission/reception beams 2 and rotates with the constant direction (a) as a shaft center, supports the back side of the reflection face 4 and therefore the reflection face 4 is turned. An angle variable drive part 9 for changing the angleθis installed on the back side of the reflection face 4. Since there is no object present in the path of the radio beam 5, a loss does not exist in the energy of radio waves. A radar device is exemplified as an application device.</p> |
