The amplitude and phase characteristics of the electric field at a finite distance from the linear and planar antenna arrays with a small number of radiators in their near field observation are theoretically investigated. It is shown that in the case of the antenna arrays lowest possible sizes of 2×1 and 2×2 radiators the field amplitude decreases uniformly with increasing longitudinal and transverse coordinates of observation points. With increasing number of radiators to 4×1 and 4×4 in the near field antenna arrays the searchlight beam is formed, in which the field amplitude decreases slightly by oscillating laws. The length of the area searchlight beam is greater in the case of the aperture antenna arrays with square-shaped aperture.

The amplitude and phase characteristics of the electric and magnetic fields in the near zone of the aperture antennas small electrical sizes are theoretically investigated. It is shown that the fields of such antennas decrease uniformly, without the formation of the searchlight beam. The searchlight beam is forming by aperture antenna with aperture of the square or round shape that bigger than one or two wavelength.

We predict an extraordinary perfect reflection of a plane wave from a finite-thickness photonic crystal made of dielectrics and metamaterials. The physical nature of this phenomenon is revealed. We show that this complete reflection is related to a resonance of surface plasmon-polariton wave along the crystal thickness.

The new models of the fractal ultra-wideband (FUWB) signals based on the set of continuous, non-differentiable functions in time domain were proposed. Using the continuous wavelet analysis method and the wavelet transform module maxima method, for each FUWB signal model proposed the time-frequency structure was investigated, the box and the regularization fractal dimensions were estimated. The peculiarities, advantages and disadvantages of each new FUWB signal model were found and discussed. The new FUWB signal models were shown to be a useful addition to the existing FUWB signal model set.

Methods of assessing the effectiveness of the protection is this: on the basis of the criterion of Neyman - Pearson obtained an analytic expression for the probability of correct detection of small terrestrial objects matrix radiometric passive-active systems in the millimeter band. This expression allows to determine the maximum signal to - noise needed for robust detection or non-detection (missing object - goals, i.e., pass the object in a given region of space, subject to availability) small-size ground targets. Also obtained the expression for radio brightness contrast, which allows to determine the maximum range of detection (not detected), which in total allows you to assess the effectiveness of passive protection of the object. Criterion of the effectiveness of remedies is loss of detection range (zoom range not detected) due to the use of means of protection of objects. As a means of protecting ground object is the use of camouflage cover in the form of radar absorbing material on a network basis, which ensures the absorption of electromagnetic waves visible, centimeter and millimeter.

The results of the theoretical investigations of hybrid microstrip patch with discontinuities as slot-meander line segment with changing period are presented. The conditions of the best impedance-matching factor with outer circuits are studied. The factor of orientation of discontinuities is investigated. It was shown that the variation of radiator's parameters allows varying the level of radiating power and the form of pattern characteristics. It is establishes that only optimum size of meander line period may realized the highest energy characteristics.

The new method of radiometric signal processing in chopper radiometer is synthesized and the new type of block diagram which realized this algorithm is developed. Unlike known types of chopper radiometers the measurements and parameter estimates at the output of radiometer do not depend on predetection section receiver instability. The simulation results confirm the findings and conclusions obtained by the statistical synthesis of radiometer by the maximum likelihood method.

Experimental results and data of numerical simulations are presented, concerning generation of wideband radio frequency (RF) oscillations in a nonlinear transmission line (NLTL) which contains a pre-magnetized core of ferrite material. Emphasis is made on the means for extracting the RF signal from the line, in order to radiate it into free space. Antennas of two types that can be used for the purpose are considered, both featuring a coaxial design. This permits availing of the principal advantages of coaxial systems, such as operation in the mode of a traveling TEM wave; wide range of the transmitted frequencies, and a reasonably simple design. The antennas studied, specifically a disc-cone dipole (DCD) and an impulse reflector antenna (`Half-IRA', or HIRA type) differ significantly in effective width of the radiated spectrum and in spatial characteristics of the radiated field in far region.

This paper presents a micro-motion detection based on coherent ultra-wide band pulse radar, in the context of improving the general imaging pipeline of through-the-wall radar. The proposed micro-motion detection principle is based on the measurement of the phase difference of the UWB carrier waveform between the transmitted and the received pulse signal. An experimental proof of concept of the proposed micro-motion capabilities is reported in this paper, with the detection of a 5mm woofer periodical micro-displacement, representing a displacement magnitude of λ/10. A radar architecture is designed to implement the imaging pipeline in real time, with this micro-motion feature. It performs 100GHz sampling frequency with an equivalent time sampling. The acquisition refreshing period of 2ms covers all biological micro-movement speed ranges.
