Information × Registration Number 0212U002353, 0111U003981 , R & D reports Title Creation of an additional antenna arrays of Giant Ukraine radiotelescope and development of new means and methods of radio-astronomical researches. popup.stage_title Head Konovalenko Oleksandr, Registration Date 10-02-2012 Organization Institute of Radio Astronomy of Academy of Sciences of Ukraine popup.description2 Are manufactured 2 additional 25-element phased antenna arrays of the Giant Ukrainian Radiotelescope (GURT) of new generation which have increased total of crossed - dipoles up to 250 (500 elementary dipoles). A band of frequencies achieve 10-70 MHz. In subarrays are applied antenna elements with the modernized vibrators, and advanced antenna amplifiers provide the greater visual field (±70 ° from zenith), high sensitivity (excess by the antenna temperature of a background over an internal noise not less than 10 dB) and a dynamic range (> 95 dB).The analog phase shifters with digital management provide overlapping of celestial hemisphere with the help of directedness diagram of the subarray. With the help of the created hardware-software means and methods the new data about a low-frequency radio emission of 40 pulsars, some hundreds flashs of active stars, and also new singularities of radiation of objects of the Solar system and Galactic are received.
