Preliminary results of the comparative analysis of Quantum Radar (QR) based upon quantum entanglement phenomenon and Noise Radar (NR) based upon classical coherence notion and correlation processing of random signals are presented in the paper. It has been shown that the basic idea of entangled multi-photon QR for simultaneous implementing of high penetrating ability of the entangled photons and high spatial resolution performance does not work because of decay of entangled state of the transmitted photons when they hits a wall, for example. QR operation abilities may be described in terms of classical physics. In addition, the multi-photon QR has been modeled by means of classically phase locked multi-frequency signals (regular and chaotic). Results of computer simulation of basic properties for such radar are presented.
