POWER FEED FOR DOPPLER VOR RADIO NAVIGATION SYSTEM AND ITS USE |
摘要 |
The device for supplying a Doppler VOR system comprises means for generating the sidebands of an amplitude modulation of a VHF carrier wave, the signals representing the sidebands being amplitude-modulated by a periodic voltage. The device essentially comprises means for coupling and means for adding the amplitude-modulated sidebands so as to produce a signal for supplying antennas having a predetermined spectrum and to compensate for the couplings which exist between the antennas. |
