摘要：

In this contribution, we present the results of the project on the development of a quantum radar using quantum illumination and biphoton states generated by spontaneous parametric down conversion. The proposed scheme enables effective target detection, determination the distance from the target, its velocity and reflectivity in the presence of intense background noise. The given scheme was shown to demonstrate significant advantage in sensitivity and accuracy of parameter estimation compared to classical analogues using coherent states. The algorithms of signal processing from the quantum radar using convolutional neural networks were developed and implemented. High effectiveness and resistance to noises even in the case of low intensity were demonstrated. In addition, detailed analysis of signal informativity of a quantum radar using mutual information and Fisher information was carried out. The results confirmed enhancement of sensibility and estimation accuracy compared to classical radars.
