FIELD: radio engineering, communication.SUBSTANCE: double-frequency localiser beacon comprises signal devices of a narrow channel and a wide channel, a linear antenna array of 2N radiating elements in a first version and 2N+1 radiating elements in a second version of the localiser beacon. The radiating elements are arranged symmetrically about the centre of the antenna array, wherein all elements and devices in the first and second versions of the double-frequency localiser beacon are made and connected to each other in a certain manner.EFFECT: reducing the number of elements of a feeder circuit of aperture control of a localiser beacon via successive addition of signals from sensors, easier adjustment of the aperture control device.2 cl, 2 dwg, 2 tbl |
