Abstract. The article describes the
approach to the choice of stochastic signals in radar and radio communications,
which is based on the concept of implementation in the process of processing
and forming of signals of artificial stochasticity, suggesting along with the
natural stochasticity (the random nature of the input signals, interference and
noise), the randomization of the conditions of "reception –
transmission" radio systems, radar and radio communications. This is
achieved by randomization is not informative parameters of the signal. The
article analyzes the conditions for solving the key problems of radar -
detection estimation and filtering related to the field of "stochastic
radar". A comparison with a "sound radar".
The fundamentals of the theory of stochastic radar,
interpreted as a new take on the conventional radar systems, but involving
artificial randomization (controlled) uninformative parameters of the signal,
for the purpose of expansion of the frequency range (base signal). The
generalized scheme of the theory, including its application for space-time
signal processing, that is - generalization to the case of spatial frequencies
(angular directions). A new scheme of splitting the observation space in
decision-making in radar with a simultaneous increase in the role of the
Observer in the theory of communication under the scheme D is presented.
Middleton. The problem of "super resolution" on the basic parameters
of the signal is considered in conjunction with the synthesis of ultra-wideband
signals for unobtrusive radars.
Keywords: the randomization of the
signal parameters, selection of the moving purposes (MTI), randomization,
stochastic sampling in time and space, noise radar.
