| 摘要 |
The present invention is in the field of satellite telecommunications, and its subject is a discriminator of millimetre radio waves, characterised in that the discrimination is carried out by the mutual locating of at least three units: a first unit 1 operating as retransmitter of a sensed frequency F1, a second unit 2 operating as transmitter of a generated frequency F2, a third unit 3 operating as receiver, the units having a spatial extent each along an axis, the distance d' separating the first unit from the second being a function of the discrimination sought, but lying between 1 and 50 mm, in that the axes 4, 4' of the first two units are mutually parallel, and in that the axis of the third unit 4''' passes through the middle of the segment S separating the first two units 1, 2. <IMAGE>
