Embodiment Construction

[0060] Firstly, the principle of navigation angle measurement in the present invention will be described below.

[0061] The correlation properties of quantum entangled microwave signals are as follows: figure 1 As shown, it represents the relationship between the quadrature components of two quantum entangled microwave signals, where a, b represent the entanglement signal, X, Y represent the direction of the quadrature component, and X a Represents the X-direction quadrature component of the a-channel signal, X b Represents the X-direction quadrature component of the b-channel signal, Y a , Y b The same is true. The orthogonal components of the same direction of the two entangled signals are respectively positively correlated and anticorrelated. In the absence of external interference, the signals measured at the same time always satisfy figure 1 Associated properties in . After receiving the quantum entangled microwave signal, the receiver can use the correlation peak d...

Abstract

The invention provides a navigation angle measurement method based on quantum entanglement microwave and a realization apparatus thereof. In this method, two paths of quantum entangled microwave signals are transmitted locally, and the time interval of the two adjacent measurements is obtained by orthogonal component correlation detection at a receiving end to further obtain a target azimuth angle. The navigation angle measuring apparatus is composed of a ground emitting part and an airborne receiving part, wherein the ground emitting part comprises an entangled microwave generator, a delay device, a horizontally polarized antenna and a vertically polarized antenna, and the airborne receiving part comprises a horizontally polarized antenna, a vertically polarized antenna, an amplifier, an oscillator, an IQ orthogonal branch detector, a data processor and a display. The safety performance and anti-interference capability during navigation angle measurement are improved, which is of great importance under complex electromagnetic environments.
