• Abstract: Both Noise Radar and Quantum Radar, with some alleged common features, exploit the randomness of the transmitted signal to enhance radar covertness and to reduce mutual interference. While Noise Radar has been prototypically developed and successfully tested in many environments by different organizations, the significant investments on Quantum Radar seem not to be followed by practically operating prototypes or demonstrators. Starting from the trivial fact that radar detection depends on the energy transmitted on the target and backscattered by it, some detailed evaluations in this work show that the detection performance of all the proposed QR types in the literature are orders of magnitude below the ones of a much simpler and cheaper equivalent classica radar set, in particular of the NR type. Moreover, the absence of a, sometimes alleged, Quantum radar cross section different from the radar cross section is explained. Hence, the various Quantum Radar proposals cannot lead to any useful result, especially, but not limited to, the alleged detection of stealth targets.

  In this paper, an explicit expression for the maximum detection range of an entangled quantum two-mode squeezed (QTMS) radar has been derived. We show that one can view a QTMS radar as a traditional radar with a reduced threshold signal-to-noise ratio. It is possible to implement a QTMS radar with a maximum detection range of up to 2km, which is suitable for recognizing small unmanned aerial vehicles at urban distances.

Our experiments extend this technique to radar data, achieving a comparable accuracy to fewshot supervised approaches for the same classification problem.
