This paper proposes usage of microwave radiation for turbine blades health/maintenance status monitoring in the course of the turbojet engine operation. It shows that it is possible to measure blade motion components using a special microwave probe, based on the homodyne detection concept. Examples of signal received from the probe during ground tests of the SO-3 turbojet engine are presented and analyzed.

Fast and sensitive simultaneous measurement of many signals by means of multi-channel coherent receiver is described. All received signals are of different modulating frequencies, synchronous to one reference frequency. The ratio of all modulating signals periods to reference period is an integer. Two practical applications of multi-channel coherent receiver are given: multipoint measurement of electromagnetic field distribution with MST method and two-channel EPR spectrometer.

The design of a wide tuning range voltage controlled oscillator (VCO) for integrated phase locked loop (PLL) is presented. The circuit was implemented on a 0.35um bicmos technology. The VCO had 36% tuning range together with good figure of merit. The paper shows the design methodology used to obtain small tuning gain variation in the whole frequency, temperature and process variation range. Some design details are shown together with measurement results.

Due to the recent advances in ultra wide-band (UWB) radar technologies, there has been widespread interest in the possible medical applications of UWB microwave radar. Therefore, the development of accurate numerical techniques to predict the propagation of UWB signals in biological tissue is of great interest to researchers as an aid in developing signal processing algorithms. Two techniques for modeling the propagation of electromagnetic (EM) waves in human tissue are presented and compared in this paper: the planar and finite difference time domain (FDTD) technique. A four layer biological model is considered, three layers of normal tissue, and one layer of cancerous soft tissue (sarcoma). The two modeling techniques are used to predict the response of the model to the UWB input signal, with particular focus on the response of the sarcoma layer. Both the Planar technique and the FDTD technique identify the presence of the soft tissue sarcoma quite easily. However the FDTD technique predicts more subtle phenomena such as multiple reflections, albeit at a high computational cost.

The property of multi-aperture irises to cause the rejection phenomena because of the interaction of two or more "iris aperture" eigen oscillations is used to propose the simplest rejection section in a circular waveguide. As an iris limiting case the set of narrow azimuth-placed arc-shaped slots with a large central aperture has been studied. Saving the low insertion loss near the stopband frequency these sections can reject the TE11 and TM01 modes totally and partially the other ones.

A modified version of iterative matrix estimator algorithm for localising emitter by intersection method is presented. The modification relies on using Tikhonov regularisation with constant parameter for computing the solutions of systems of linear algebraic equations obtained in subsequent iterations of corrections to the first-guess emitter position estimate.
