A mathematical model of autodyne turbine engine vibration sensors was developed. Oscillator power supply noises were taken into account. The analysis of autodyne and noise characteristics was carried out. The main requirements to the choice of the operation point and to the level of reflected radiation for various characteristics were formulated. The results of experimental research were obtained on the example of “Tigel'-08” autodyne oscillator for 8-mm wave band. Obtained results confirmed the conclusions of theoretical studies.

The effect of spatial correlation on the capacity of MIMO system and bit error rate is discussed. A method of optimization of multi-element antenna geometrical parameters under given power azimuth spectrum is proposed. It is shown that MIMO system with optimized antennas provides better performance as compared with MIMO system using standard half-wave uniform linear arrays, when V-BLAST coding algorithm is implemented in a channel with correlated Rayleigh fading and Gaussian noise.

The temperature influence upon the shielding characteristics of flexible water-containing nanocomposite shielding materials on a textile base is studied in the frequency range of 8-12 GHz. Application of porous materials with a highly developed surface, as well as nanostructuring additives and components for the solution prevents the nanocomposite water-containing materials from shielding efficiency deterioration at temperatures below freezing point.

A prototype of the sounding-pulse generator unit for mesosphere-stratosphere-troposphere ultra-high frequency radar (MST radar) has been developed. The pulse generator has the following technical specifications: the output frequency range of 40-60 MHz; the output power not lower than 1 W; the RF pulse length from 0.1 to 50 μs; the interpulse interval from 2 μs to 60 μs. The RF pulse envelope can be of different shape: rectangular, trapezoidal, Gaussian etc. The RF pulse bursts can also be generated with the phase modulation using the Barker code or other codes.
