Abstract:

In the radiophysical interpretation of a new developing direction (quantum radar), a probabilistic approach is used, in which the result of observation, as in quantum physics, is described with fundamentally irreducible uncertainty, and is not in a single basic state. With this approach, a radar target acquires the status of a collective system with an obvious entanglement of target scattering singularities, and a significant contribution to such entanglement is added by the target's own noise, as well as interference, which should be considered in this case as an unidentified collective (in the sense of quantum physics) quantum mechanical environment. At the same time the radar portrait of the target (the observed interference pattern) appears to be “proportional” to the probability density of the distribution of entangled quantum objects in the field of the pattern. This probability density corresponds to the square of the modulus of the “probability amplitude” – a complex quantity responsible for coherent effects in the language of probability distribution of quantum objects. Great importance in the “unraveling” of quantum entanglements in quantum radar is attached to ensuring and maintaining the coherence of the states of entangled quanta, manifested in the results of evaluations of signal objects. Taking into account this circumstance, it is of interest to analyze the budgets of incoherent and coherent integrations of radar signals to be adapted in quantum radar to the features of coherent states.

The goal of the article is obtaining estimates of achievable resources (characteristics) of typical incoherent and coherent integration procedures used in radar channels when normalizing integration results relative to the number of integrated coherent states.

Typical integration procedures and sources of losses have been considered. Estimates of achievable resources (characteristics) of typical incoherent and coherent integration procedures used in radar channels have been obtained. The balance of resources (budget) of incoherent and coherent integration procedures used in radar channels for typical integration schemes has been determined.
