In our work is demonstrated the method that can help to predict the existence of distant objects in the Solar system. This method is connected with statistical properties of a heliocentric orbital complex of meteoroids with high eccentricities. Heliocentric meteoroid orbits with high eccentricities are escape routes for dust material from distant parental objects with near-circular orbits to Earth-crossing orbits. Ground-based meteor observations yield trajectory information from which we can derive their place of possible origin: comets asteroids and other objects (e.g. Kuiper Objects) in the Solar system or even interstellar space [12]. Such information is important at planning space missions. We analyze elliptic meteor orbits with high eccentricities that were registered in 1972 - 1978 in Kharkiv (Ukraine). Statistical distributions of radius-vectors of nodes and aphelia of orbits of meteoroids contain key information about position of greater bodies. We discuss the accuracy of the ground-based radar observations of faint meteors. An estimation of selectivity factors of meteor radar measurements is made on base of radiophysical and astronomical researches of meteoric substance and its interaction atmosphere of the Earth.
