Item InSAR геометрия и базови операции(Бургаски свободен университет, 2010) Лазаров, АндонIn the present work based on geometrical interpretation of Inverse Synthetic Aperture Radar (InSAR) scenario, main parameters, characteristics and operations over InSAR data are defined. SAR interferogram and interferometric phase SAR equations are derived and procedure of interferogram flattening is given. The procedures of terrain motion evaluation and differential interferogram generation are presented. Basic operations including rectification of the elevation map, co-registration, and coherence evaluation, and phase unwrapping are discussed. Numerical experiment is carried out to verify geometrical interpretation of the interferogam generation and main operation performance.Item ISAR image reconstruction algorithm(Бургаски свободен университет, 2010) Лазаров, АндонThis paper deals with generalized ISAR geometry and image reconstruction technique. Three-dimensional (3-D) ISAR scenario is projected on two-dimensional (2-D) radar registration plane. The arbitrary movement of the object is decomposed into two components: radial displacement of the object’s geometric center and rotational movement around it. It is proven that the demodulated ISAR signal, reflected from the target during aperture synthesis, can be considered as 2-D Fourier transformation of the image function, corrected by an exponential term and as a consequence, the image function can be extracted by 2-D inverse Fourier transformation of the phase corrected ISAR signal. Numerical experiment validating aforementioned statements is performed.Item SAR модел на процеса на изобразяване(Бургаски свободен университет, 2010) Лазаров, Андон; Минчев, ДимитърThis work addresses the model of SAR imaging process. SAR Geometry with thoroughly mathematical description of the observed surface is suggested. SAR emitted signal with linear frequency modulation is used to produce reflected by surface SAR signal model presented as four-dimensional array (matrix) and generated by Hadamard product with special defined rectangular function. Two-dimensional Fourier transform is applied to obtain single look complex image, which can be used to generate interferograms. To verify proposed geometrical and signal models a realization of the processing chain, implemented in MATLAB environment is illustrated.Item TAKING AD(VANTAGE) OF WORDS(Бургаски свободен университет, 2010) Попова, ДиянаThe paper looks at how advertising, which occupies a controversial place between art and business, makes use of words to achieve its goals.

Field research was carried out in July 2009 which examined the judgments on cases of placement of minors and adolescents in the social-pedagogical boarding school in the village of Lik and the correctional boarding school in the city of Rakitovo. The minors and adolescents placed there represent more than one fourth of all children living in such institutions for the same period in 2009. In addition, some other 54 judgments pronounced in the period of 2005-2010 by the district courts around the country have been examined. The analysis aimed at establishing the extent to which the guarantees for protection of minors’ and adolescents’ rights have been strengthened after the introduction of a court procedure for placement in correctional institutions. The conclusions from the conducted research are that the judgments themselves do not allow to form an objective opinion about the extent to which the legislative amendments have created better guarantees in practice for effective protection of minors’ and adolescents’ rights during the holding of court hearings, even when a lawyer or a trusted representative have been ensured. Moreover, the courts lack an objective criterion on how to choose between placement in social-pedagogical boarding schools and in correctional boarding schools, which results in placement in one and the same institution of children having committed acts with different level of severity.Item Диалогичното и/в монологичното(Бургаски свободен университет, 2010) Люцканова, ЦонкаThe aim of the study is to present determinants of the dialogue as well as of the monologue in the speech communication.
