Specific embodiment
Navigation angle measuring principle during explanation is of the invention first below.
The associate feature of quantum entanglement microwave signal as shown in figure 1, it to illustrate two-way quantum entanglement microwave signal orthogonal
Relation between component, wherein a, b is represented and is tangled signal, X, and Y represents quadrature component direction, XaThe X-direction of a roads signal is represented just
Hand over component, XbRepresent the X-direction quadrature component of b roads signal, Ya、YbIt is such in the same manner.Two-way is just tangling the same direction of signal
Handing over and positive association and anticorrelation are shown as respectively between component, in the case of without external interference, the signal that synchronization is measured is all the time
Meet the associate feature in Fig. 1.After receiver receives quantum entanglement microwave signal, using the method for correlation peak detection to which
Measure, the correlation peak of maximum when detecting to propagation time identical two paths of signals, can be obtained；If two paths of signals
Asynchronously reach, then because of the characteristic with completely random between tangling microwave signal each, not there is no correlation in the same time
Property, cannot get correlation peak.
As shown in Fig. 22 points of A, B is to tangle the transmitting terminal of microwave signal, in the case where there is no time delay in two paths of signals,
Signal is launched from antenna to free space, forms the wave beam shown in figure, and the associate feature due to tangling microwave signal connects in AB
On the perpendicular bisector of line, the two paths of signals that receiver is received is associated everywhere, and, root then uncorrelated in other any positions
According to this principle, the perpendicular bisector of AB lines can be demarcated.
After certain delay process is carried out to A roads signal, the space time correlation point of two-way quantum entanglement microwave signal will be sent out
Raw skew.Fig. 3 shows the schematic diagram to needle position misalignment after the process of A roads signal lag.After the emission delay of A roads signal, it is clear that
The relating dot of two paths of signals to A points side offset, no longer occur on original perpendicular bisector, in practice AB point-to-point transmissions away from
It is negligible from working region is compared, it is assumed that detect two paths of signals at the C points in figure while reaching, it is believed that two
Road signal is parallel with the line of C points, then the two paths of signals on OC lines is associated everywhere, other positions then not phase
Close.In the same manner, if delay process is carried out to B roads signal, relating dot can be offset to B points side.Therefore, can be according to actual need
Will, change the time delay size of signal, demarcate any baseline.
On this basis, if continuously changing the time delay of A, B two paths of signals in transmitting terminal, then the effect of formation equivalent to
Association baseline comes and goes scanning in the working region, if being applied to the aircraft landing stage, ground installation is transmitting terminal, runway centerline
Overlap with AB perpendicular bisectors, airborne equipment is receiving terminal, then can pass through survey aircraft it is adjacent measure twice association baseline when
Between interval obtaining azimuth of the aircraft relative to runway centerline, so as to vector aircraft safe landing, as shown in Figure 4.
Fig. 5 shows the schematic diagram of fundamental wave beam-scanning method angle measurement when carrying out to aircraft.The perpendicular bisector of Fig. 4 to AB points is defined
For 0 ° of course angle, when associate the relative runway centerline of baseline with fixed speed aircraft is encountered in " past " scanning from left to right when, fly
Machine receives " past " pulse, the i.e. relevant peaks of coherent detection；When " returning " scanning then from right to left and encountering aircraft, aircraft is again
Receive " a returning " pulse.Adjacent correlation peak time interval twice be t, due to associate baseline sweep speed it is very high,
The displacement of angle measurement receiver can be ignored in one scan period, time interval t between this pair " toward " " returning " pulse with run
The relational expression of the relative bearing of road center line is
In formula：θ azimuth of targets (°)
The sweep speed (°/s) of V association baselines
T0The two-way time for associating the inswept runway centerline of baseline is poor (s)
