Future prospects of creating bursting radar technologies within the scope of a new interdisciplinary scientific trend

In processing digital images of different physical origin, it is frequently necessary to eliminate from analyzed fragments the spatially uncorrelated additive noise resulting usually from imperfect recording process. Fast algorithms for calculating geometric characteristics of such connected noise regions are proposed and program-implemented. The obtained results were used to construct optimal rank filters intended to detect and suppress the noise.

A method for lossless compression of palletized synthetic images is described. The method bases on hierarchical image representation as a set of matrices or hierarchical levels (HL) of a reduced size and on storing only information required to reconstruct a current HL from the calculated values of previous HLs. Different versions of implementing the method are considered. Some of them exploit actively peculiarities of cartographic images. Experimental investigation shows advantages of the method over the well-known lossless compression standards.

The role of nonlinear wave processes of radiation and propagation of elastic oscillations in improving the quality of data processing in physical experiments is considered. Analysis of seismic waves without loss of generality of results relative to waves of another nature is carried out. The data were obtained in seismic physical experiments on depth sounding of the Earth by elastic oscillations generated by powerful surface vibrators developed by scientific institutions of the Siberian Branch of the Russian Academy of Sciences. The efficiency of the proposed approach to data processing is substantiated by the higher measurement accuracy of seismic wave parameters and by results referred to determining by daily and semi-diurnal periodicities of lunar-solar tides in seismic field parameters, which were obtained for the first time.

Characterization of micro objects of different nature, particularly their geometrical properties, is an important issue of today

A theory of right-hand solutions for one class of differential equations which the Lagrange systems of the second kind with discontinuous controls are reduced to is developed. The structure of controls is defined from the solution of the problem of synthesizing control systems for mechanical objects on the basis of the decomposition principle. An implicit method for single-valued definition of controls at discontinuity points is proposed. General issues of existence of right-hand solutions and their properties like uniqueness, continuation, stability, and continuous dependence on the initial conditions and parameters are studied.

Results of researches on using modern information technologies in the field of designing the means for training cadets to skills of subdivision control in combined arms operations are presented.
