conditions (in the absence of a power supply line), the whole spectrum of the
adaptive identi
er is realized in real-time mode. Otherwise, the results of the
measurements are stored in an off-line storage unit and are processed later.
The algorithmic support of Adaptive Identi
er is based on a complex application
of methods of recognition and classi
cation of discrete images formed on the basis
of 35 spectra registered during a
fixed period of time. A time interval of 1 s is
usually established and provides about 60 values of brightness for each of the 35
optical channels. The spectra obtained are sources of sets of statistical parameters
and different characteristics united into vector spaces for their comparison with
standard samples stored on the computer. The technology of this comparison
depends on the diversity of identi
cation methods.
er is designed to learn from the measurement of spectral
characteristics and the simultaneous independent measurement of the content of
chemical elements in the aquatic environment. As a result, a standard bank is
formed in the knowledge base, the comparison with which provides the solution to

er solves these problems by real-time monitoring
of the aquatic environment. In the stationary version, it allows the tracking of the
dynamics of the water quality in a stream, and when placed on a ship, it allows the
measurement of water pollution parameters along the route.
The functionality of the adaptive identi
er can be extended by increasing the
volume of standards in the knowledge base. The use of a natural light source allows
the examination of soils, the identi
cation of oil products on a water surface, the
determination of the degree of pollution of atmospheric air and the estimation of the
conditions of other objects of the environment, whose spectral images may change.
That is why the adaptive identi
er is a universal measuring device the use of which
in the monitoring system allows one to have operative information, not only on the
arising of oil pollution, but also about other pollutants which may appear in the oil
and gas extraction zone.
4.11 Adaptive Technologies and Sea Navigation
The GIMS technology is instrument for the increase in effectiveness of decision
making under management complex processes and systems subjected to the
in
uence of external factors and being in steady development or moving. One of the
GIMS application areas is sea navigation where management of physical system
ship-sea is connected with solution of many tasks in operative regime of mea-
surement and identi
fl
cation of environmental characteristics. Remote hydrophysical
experiment is more reliable method for the control and management of ship-sea
system (Krylov et al. 1981).
