基于几率波探测下的量子雷达系统原理

The principle of the quantum radar system based on the probability wave

从技术体制上划分,量子雷达分为有源量子雷达和无源量子雷达.根据探测波是实波还是几率波,有源量子雷达可分为实波量子雷达和几率波量子雷达.量子雷达还可分为线性量子雷达和非线性量子雷达.非线性量子雷达根据探测波采用纠缠光子和干涉几率波的不同而分为两种;还可进一步分为测回波和不测回波两种.利用几率波在空间的几率关联特性,通过对本地几率波的测量而获得空间的目标信息.为此我们将量子光栅与超导单光子探测器相结合,提出一种新型的、更高效的单光子检测器件,用于实现这种新型、不测回波信号的有源量子雷达.这一技术使量子雷达性能产生了巨大提升.

In the technical system,the quantum radars are classified by the active quantum radars and the passive quantum radars.The active quantum radars are divided into real wave quantum radars and probability wave quantum radars according to the probing wave type.The quantum radars are further grouped into linear quantum radars and nonlinear quantum radars.The nonlinear quantum radars have two types based on the entangled photons and the interference probability wave.The nonlinear quantum radars are subdivided into two type that is with or without the photon echo checked.In the present work,the probability conservation appearing in the probability interference wave is applied to detect the target in the space through measuring the local wave.A novel and high efficient single-photon detector is developed combining the quantum grating with the superconducting single-photon detector and employed in the quantum radar not receiving echo.The quantum radar technology is highly promoted.
