Information × Registration Number 0213U000298, 0110U000035 , R & D reports Title Development and application of elements and systems of large antennae of the decametric range. popup.stage_title Head Falkovich Igor, Registration Date 30-01-2013 Organization Institute of Radio Astronomy of Academy of Sciences of Ukraine popup.description2 Development of small antenna elements for large arrays on the basis of short "thick" vibrators is continued. Principles of construction of new complex for measuring of Frenel coefficients and complex dielectric constant of the ground are offered. Elements and knots of the largest in the world radio-telescope UTR-2 are developed and modernized. The highly precise radiometer with parameters exceeding one of radiometers made abroad is developed and made. Possibilities of improvement of large antenna parameters by using a new principle for minimization of side lobes of diagram pattern are theoretically investigated. New techniques for carrying out radio astronomy observations on the radio telescope UTR-2 and antennae of interferometric system URAN are offered and probed. Product Description popup.authors І.С.
