A process of extrapolation of polar coordinates with data in changeable length.

A method of separating polar coordinates into several components has been devised. According to this method polar coordinates can be extrapolated by means of data in changeable length. Based on a wealth of testing calculations an empirical criterion has been concluded for data length. With this criterion and by the method to extrapolate polar coordinates, the extrapolation precision of between 0″017 and 0″030 can be obtained in most of the cases.
