Near-Earth Objects: Radar Observations
Scientific paper
Radar astronomy paradox (RAP): practically everybody agree with essential contributions of active radar observations to Solar System and especially to near-Earth object (NEO) explorations, but despite everything prefer to develop new and new passive telescopes and disposable space missions, only, and nobody want to build at least one dedicated multipurpose radar telescope (neither Arecibo nor Goldstone and Evpatoria radars were created as dedicated radar astronomy instruments). Also, as of June 2002, among of 188 radar detected asteroids and comets there are only 3 NEOs, which were investigated in Europe, with single European radar facility, sited in Evpatoria. The main reason of such deep gap is a low sensitivity of Evpatoria radar, which is in 10 and 300 times less powerful than Goldstone and Arecibo. Therefore, I guess the first dedicated European NEO Radar (ENEOR) is earnestly needful now. From time to time we discuss this problem, but it is not solve for the present moment, perhaps because of above formulated RAP. Origin and concept of the ENEOR, as well as the ENEOR project, based on the being under construction 64-m Sardinia Radio Telescope, will be presented below.
