A novel method for super resolution in the grayscale images and video sequences is introduced. In difference with conventional approaches, where the procedures use small pixels spatial information in the vicinity around the positions of the interpolation, a new framework employs the spatial spectral properties of an image or sequence applying wavelet transform technique. Novel wavelets based on atomic functions, which are used here, have shown good properties of resolution by extension of an image size up to 4 times in comparison with the original low resolution image reconstructing three new pixels should be estimated for each one existing pixel. Numerous statistical simulations have demonstrated the effectiveness of the novel technique, exposing an excellent subjective visual quality, as well as significant improvement of super resolution image in terms of objective criteria in comparison with better existing algorithms.

This paper describes the results from experimental studies on the coherent Doppler radar signals echoed from a human being. Spectral and temporal realizations of informational processes and their statistical characteristics are presented. It is shown that in the microwave-band sounding signal the process generated by the echo-signal phase modulation caused by human breathing has the properties of periodically correlated random process. The statistical characteristics of this process are calculated on an equidistant grating, the period of which is equal to that of process correlation. A stochastic criterion is proposed to estimate the correlation period. The ergodicity property of the process on an equidistant grating has been theoretically proved and experimentally confirmed.

The development of compensation system of the Doppler frequency shift of the reflection from the sea surface. The interference spectrum narrowing is experimentally discovered. It makes possible to improve the interference reflection factor up to 2...6 dB. It is shown that implementation of the compensation will cause the dynamic band of distribution function to compress at output of the selection filter. As a result the signal-to-noise ratio gives an additional increase from 1.5...3.5 dB to 3...8 dB for falshe alarm probability 10−2 and detection 0.9 and 0.5 respectively. The using of that selection system to the side-looking radar allows us to improve a noise suppressing and to perfect an object observativity up to 8... 13 dB.

A sensor of movement based on a biconical coaxial microwave resonator is considered. Electrical field structure and basic electrodynamics parameters of the biconical coaxial microwave cavity have been calculated with finite element method. The influence of various technological defects and geometrical parameters of the biconical coaxial on the sensor properties has been investigated. It has been determined that form variation and transversal displacement of the internal conductive rod of the resonator have produced maximal influence on the sensor parameters.

A modified broadband strip method has been used to measure the enhancement of dielectric constant of metallodielectric substrates made from one layer of parallel Fe-wires embedded inside a layer of resin, made by a wax rapid prototyping machine. The devices design has been simulated by using FDTD method for parallel and vertical orientation of the wires under the strip (wire). An enhancement of dielectric constant of the substrates with wires inside wax has been verified from S-parameters measurements in both cases relative to the substrate made by only wax and same dimensions. The enhancement of dielectric constants with the change of Fe-wires diameter has been also calculated for free space geometry and for comparison of results.
