A new filtering method of the single-photon quantum radar detection
With the rapid development and widespread application of stealth technology,stealth weapons ex-hibit significant advantages in terms of penetration capability,survivability,and precision strike ability,which poses challenges to anti-stealth air defense combat.Quantum radar,a new radar system that utilizes quantum phe-nomena for target state sensing and information acquisition,has been explored by scientific research institutions in many countries in the past decade.Firstly the current research progress on quantum radar is reviewed,and then a new detection approach is proposed.It employs non-traditional filtering technology to alter the state of the quan-tum state of a transmission channel,and utilizes entangled photon states for joint measurement to get a method that can improve the reflection or transmission performance of target absorbing materials.This operation provides a new solution for quantum radar measurement design.
