Abstract
A method and apparatus for authenticating a radar return signal include: generating an outgoing radar beam; generating a pair of entangled photons comprising a signal photon and an idler photon; combining the signal photon with the outgoing radar beam to generate a combined beam; sending the combined beam towards a target; receiving a return beam; detecting the signal photon from the return beam by a quantum illumination receiver; and making a joint detection with the idler photon.
Claims20
A method for authenticating a signal, the method comprising:
- generating an outgoing pulse signal;
- generating a pair of entangled photons comprising a first photon and a second photon;
- combining the first photon with the outgoing pulse signal to generate a combined beam;
- sending the combined beam towards a target;
- receiving a return beam;
- determine whether the return beam includes the first photon;
- and
- authenticating the return beam when the return beam includes the first photon.
