From two points of the radio compass (as is, see below), with the base distance L between the points, towards the radio beacon station two continuous signals with frequency modulation with unilateral saw-toothed linearly incremental law (LLFM signal) are radiated, with close frequencies f1 and f2 of LLFM signal and identical wit its modulation frequency Fm and frequency deviation dfm, which are: received on the beacon, amplified by power and re-radiated towards the radio compass, where they are multiplied with radiated LLFM signals and the following signals are selected: Fpi=2DiFmdfm/C-2Vif1/C and Fpj=2DjFmdfm/C-2Vif2/C, where Di and Dj - the distance between radiocompass antennas and the radio beacon station antenna moving at the velocity Vi, C - speed of light, and then, after multiplication of signals with the frequencies Fpi and Fpj, the difference signal is selected with the frequency f3=Fpi-Fpj, the value of which, at coincidence of the line of radiocompass antennas arrangement with the direction towards beacon, or perpendicular restored from the middle of the line of arrangement of radiocompass antennas, with the direction towards the beacon, irrespective of distance between the radio compass and beacon, is certain and allows to be sure, that at detection in the radio compass of the signal with the frequency f3, the direction towards beacon is identified. The radio compass contains the radio beacon station and double frequency range finder with two antennas set on the base distance L to each other, the difference frequency filter outputs of which, through the series connected and narrow-band pass filter, are connected to the circuit of alarm system enabling. And the radio beacon station contains antenna, bandpass filter and power amplifier. |
