David M.P. Smith, Michel J. Arts, Albert-Jan Boonstra and Stefan J. Wijnholds, "Characterisation of astronomical antenna for space based low frequency radio telescope", IEEE Aerospace Conference, Big Sky, MT (USA), 2-9 March 2013 abstract: The Orbiting Low Frequency Antenna for Radio Astronomy (OLFAR) project is a feasibility study investigating a low frequency radio telescope in space using a swarm of autonomous nano satellites. Due to ionospheric interference found at frequencies below 30 MHz, such an instrument is not feasible on earth. The effect of the non-symmetrical deployment of the antenna and the effect of the non-uniform dimensions of the satellites on the antenna properties are investigated. |
