Two configurations of DLAs are considered, namely: two-shell circularly-layered lens excited by a horn antenna and shaped homogeneous flat-bottom lens excited by an array of printed feeds. Synthesis of the antennas is carried out in the 2-D formulation using highly-efficient in-house softwares based on rigorous mathematical approaches (Mie-type series solution for the former and Muller's boundary integral equations for the latter). It is demonstrated that simultaneous optimization of lens and feeding structure parameters enables one to design a beam-switching DLA with improve performance characteristics (boresight directivity and steering ability) using standard low-loss dielectric materials.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114701676","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}

It has been shown, that extension of reactive field region significantly depends on the illumination law especially for small radiators. The ratio between the reactive and active power density has been calculated and analyzed at different planes in near-field region as well as along the axis normal to radiator aperture. It has been shown that, the reactive component of power flux density was absent in all planes of observation in sections |x|=|y| for the uniform amplitude distribution. The pattern of the spatial distribution of reactive power component is symmetric with respect to sections |x|=|y|.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123118152","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}

It is shown that the probability of correct recognition is extremely high >0,95 for high-altitude cumulus clouds even in the case of small AR model order and the probability is some worse for cumulonimbus clouds. 4. In the case of the “angel-echo” the probability of correct recognition is lowest because diffuse scattering from the “angel-echo” cannot be satisfactory described by a set of harmonic oscillations which are typical for the AR model.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126332365","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}

Heliograph of radio decameter wavelengths 无线电十米波长的日光照相仪

{"title":"Heliograph of radio decameter wavelengths","authors":"A. Koval","doi":"10.1109/MSMW.2010.5546057","DOIUrl":"https://doi.org/10.1109/MSMW.2010.5546057","url":null,"abstract":"The heliograph of radio decameter wavelengths started to be created and developed else in 1976 on the base of antenna system UTR-2 (Ukrainian T-shaped radio telescope). Basically, the main features of the heliograph are determined by the characteristics of UTR-2. To observe stars, Sun, planets and others within the frequency range 10 – 30 MHz, the radio telescope forms five independent pencil-shaped beams with angular width 25′ × 25′. The scanning of sky area is provided discretely in declination and hour angle. The sensitivity of heliograph is about 104 Jy (1 Jy = 10−26 W/m2/Hz). At first the radio astronomy observations by the radio telescope UTR-2 (and the heliograph too) were carried out at a few discrete frequencies. This led to difficulties in distinguishing solar burst features (for example, fine structure of the solar Type II bursts and so on) with confidence. Last time the facilities of radio telescope UTR-2 have been essentially extended due to an effective broadband telescope amplifier system and a new back-end. Now the observations are conducted by means of the DSP (digital spectrum processor) in the frequency band of 16.5 MHz divided on 4096 channels. Therefore, the basic scheme of the heliograph and its properties have been improved.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122019968","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}
