Inverse-distance spoofing safety ranging system based on quantum technology, and ranging method thereof

Abstract

The invention relates to an inverse-distance deception safety ranging system based on a quantum technology, and a ranging method thereof. The inverse-distance deception safety ranging system based onthe quantum technology is composed of a quantum state preparation system, a transmitting and receiving system, a quantum state detection system and a computer integrated analysis system. The quantum state preparation system prepares a quantum state and encodes the quantum state; the transmitting and receiving system transmits and receives encoded quantum state signals; the quantum state detectionsystem identifies an echo signal quantum state, and the integrated analysis system conducts integrated analysis on an identified echo signal. The quantum state preparation system prepares a quantum polarization state and encodes the quantum polarization state, when the enemy receives and replicates the signal, the quantum state of the signal is interfered, and thus the signal error rate is increased; and deception interference behaviors of the enemy can be identified by analyzing the error rate of the echo signal, and finally the misjudgment probability of enemy targets is decreased. Accordingto the inverse-distance deception safety ranging system based on the quantum technology, and the ranging method thereof, the purpose of absolute safety and high-precision ranging are achieved.

Description

Technical field: [0001] The invention relates to laser countermeasure technology, in particular to an anti-distance deception safe ranging system and a ranging method based on quantum technology. Background technique: [0002] Laser technology has developed rapidly over the past few decades. As an important part of the weapon system, laser devices have been widely used in the military, including rangefinders, target designators, guided missiles, communication devices, reconnaissance equipment, etc., which greatly improve the combat performance of the weapon system. For example, the laser range finder has greatly improved the first hit rate of the artillery, and the use of laser-guided weapons to achieve precise strikes on specific targets. In order to combat the increasingly serious laser threat in modern warfare and future battlefields, countries are accelerating the development of laser countermeasure technology. Laser deception jamming technology is one of the contents ...
