The results of experimental study of backscatter spectral -polarization features from above-water and surface objects are presented. Investigations were carried out with coherent systems both with the pulse and CW modes of millimeter and centimeter wave bands (from 10 sm to 2 mm). The informative features are concerned with modulation both the amplitude and Doppler translation are condition on modulation of scattered signal at the stroke rate for the oared boat and the frequency modulation concerned with hands and lags move of moving man as well are ascertained. For the scattering from the object body the small level of depolarization factor of the scattered signal is typical. Ascertained that for the coincident by frequency spectral components of the signal scattered from the objects on orthogonal polarizations the high values of cross correlation factor is typical.

Mutual coupling causes in small antenna arrays distorted and correlated element patterns. To have more identical and ideal element patterns the array can be corrected computationally with a correction matrix. For microstrip arrays a new method to find a reference plane for pattern correction which uses the measured scattering matrix is presented. The method determines an optimum reference plane for which the imaginary part of the mean pattern correlation has a minimum. The computation is completed over a frequency band. The method is evaluated using several microstrip arrays with element spacings 0.3lambda ... 0.9lambda.

The hyperthermia (HT) treatment experiences in MSC MCC during years 1989-2006 has been described shortly. They included mainly, in chronological way, research on the prostatic and cervix cancer, employing superficial and intra urethral microwave HT, using BSD-300 and specially designed transurethral applicators as well as 500 kHz HT with original device HT-2. Especially promising results have been obtained for patients unfit for standard gynecological brachytherapy if synergy of HT and brachytherapy were applied.

Paper presents a proposal of method for closely spaced paths mitigation for indoor location system based on spread spectrum signals. At the beginning issue of closely spaced paths influence for the accuracy of TO A determination is explained. In the following part results of indoor propagation simulations are presented. These simulations show relationship between delays and directions of arrival of power delay profile components. The proposal of simple four-element null steering antenna array, which can mitigate this effect, is proposed. The paper contains also results of measurements showing influence of multipath propagation to coarse code synchronization.

At present the technology of identifying the objects by their radiation in radio band is developing rapidly. The use of submillimeter band allowed approaching the radio bright image to the photographic one. The use of decimeter and centimeter bands allowed identifying the objects under ground. In the article the theoretical foundation of identifying and recognizing objects on the ground, on water and under ground is presented. Estimated values of radio bright contrasts of various objects on the surface and under surface of the ground are presented. In the article the results of flight (aircraft and space) experiments of measuring radio bright image over ground, above water and under ground are given.

The paper presents an approach to microwave image reconstruction. The approach is based on scalar integral scattering equation under Born approximation. Scattering equation in discrete form is reduced to the system of linear equations, which is solved to obtain object image. Scattered field data gathered using multiple incident frequencies were used. Tikhonov regularization is used to overcome problem ill-posedness. It's shown that using approach proposed allows achieving better radial resolution compared to frequency domain approach.

This paper presents the investigation results on the effect of separate element dimensions on the radiation characteristics of coaxial X-band monopole antenna. In particular, the variations of monopole height, ground-plane dimensions, and monopole location relative to the ground plane are analyzed in details. Based on FDTD simulations a contribution of EM fields scattered by these elements in the radiation pattern formation has been shown. As a result, the regularities in the elevation angle of peak directivity changing have been determined.
