Abstract

In this article, an elegant methodology to correct the positioning errors of the focalization system in a radiotelescope is presented. Two different solutions are presented in two bands. In one case the solution is highly stable with tolerance positioning. In the other solution, the tolerance in the positioning and the focal distances of the lenses are very low. But a method to correct these tolerance problems and getting the accurate focalization parameters of the radiotelescope is proposed. New 40 m radiotelescope of the National Observatory (Spain) is used to validate results. (C) 2006 Wiley Periodicals, Inc.
