The purpose of this article is the analysis of a priori uncertainty elimination methods in a poorly studied processing experimental results interpretation under conditions of limited a priori knowledge about research process models. Two modern adaptive methods that can be used at experimental data preprocessing stage: empirical mode decomposition and singular spectral analysis (caterpillar) are presented...
Our goals consist in designing and realizing a Ultra Wide Band (UWB) radar for a medical application. On this basis, we study in this contribution the interaction between the radar's electromagnetic pulse and the human body layer in a UWB frequency range. Indeed, this study helps us to design this radar system and prove the possibility of taking an image of each human body layer by exploiting the...
In this paper, the disadvantages of using the Hough transform as a detector have been considered in a search radar. To illustrate the effect of these disadvantages on the performance of the detector, its performance has been compared with the optimum detectors. To do this, the Generalized Likelihood Ratio detector has been extracted for detecting a target line with unknown normal parameter pair in...
Continuous monitoring of atmospheric opacity at 22 GHz and 36 GHz, ground meteorological parameters and atmosphere models allow separating absorption in water vapor, oxygen and hydrometeors and predicting atmospheric opacity at RATAN-600 radio telescope in wide band. Design, features and parameters of radiometric modules at 22 and 36 GHz for effective continuous monitoring of atmospheric opacity are...
This paper is dedicated to investigation of the polarization characteristics of multipath signal in order to distinguish a multipath signal from a direct one, Linear Depolarization Ratio is proposed to be used as an indicative parameter in this task. Modelled and experimental results of multipath signal reception are present in this work.
