The globality and efficiency of the survey is provided by the placement of radars on aerospace carriers. At the same time, there has been a proliferation of side-scan radars (providing a wide viewing range with a low spatial resolution) and antenna aperture synthesis radars (these provide high resolution in spatial coordinates, which depends on the type of survey). Radars used for imaging are classified according to various characteristics determining their advantages and disadvantages. Among such features, we can also distinguish the radar viewing area, which is currently limited to angles of 15° to 60° to the right and left of the observation in the nadir. The viewing range from -15° to + 15° from the nadir is characterized by a low resolution in range and traditionally is not visible by these radars (the socalled “blind zone”). In this regard, an alternative system for building radar images from aerospace carriers is proposed. It will provide imaging with high angular resolution of the viewing range from -15° to + 15° from the nadir. The main feature of the developed radar lies in the signal processing algorithm that combines methods of active (the presence of probing UWB signal) and passive (aperture synthesis) radiolocation. In addition, the radar implements a new method of “spectral aperture synthesis,” which allows the transition from processing of UWB signals with the continuum spectrum to processing multi-band signal processing.","PeriodicalId":167305,"journal":{"name":"2018 9th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117078998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, the use of ferromagnetic nanoparticles in the medical therapy of cancer requires the development of new methods control their synthesis. Development of microwave control methods and visualization systems can be a promising direction in the development of synthesis technologies and stabilizing of inorganic suspensions of nanoparticles. The original hardware-software system for the study of physical and biological objects in a wide frequency range is created. The system has frequency range from 54 to 6800 MHz and the sensitivity up to 70 dB. Also, the compact microstrip patch antennas and directional couplers for carrying out researches in a wide band range were developed. Visualization and evaluation of the state of the samples was carried out in accordance with measurements of scattering in the near-field zone.","PeriodicalId":167305,"journal":{"name":"2018 9th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129751917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relevance of using Barker codes as generating sequences of a composite code intended for generating a synchronization signal is shown, without limitations on the choice of the shape of elementary symbols. The possibility of synthesizing composite sequences with given properties by an adequate choice of elementary symbols and generating sequences is investigated. It is shown that the use of Walsh's orthogonal sequences as elementary ones, introduces the self-synchronization property in the composite Walsh-Barker sequences and a number of new beneficial properties. The orthogonality property of the Walsh sequences and the orthogonality properties of the composite sequences can be simultaneously transmitted on a single carrier of several composite signals, modulated by information symbols. To allocate transmitted information symbols, the matched filtering of the transferred sum is used. The article is followed by diagrams obtained by simulating processes and sequences using the Hewlett Packard © HPVEE Visual Object-Oriented Programming Package. The possibility of simultaneous and independent transmission of various modulated composite sequences are proved. The possibilities of the practical application of composite sequences in perspective telecommunication systems are estimated.","PeriodicalId":167305,"journal":{"name":"2018 9th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128462538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
