Inverse Scattering: Ionospheric Structure Determination

Abstract

A paper entitled 'Curved Space Scattering' has already been sent to AFOSR. The abstracts of the paper and report contain statements of the research accomplished. In addition we have looked into the following problems: a. We have employed the Kanal-Moses variational principle to treat the synthetic data discussed in the report listed in 1.1. It was found that if the initial trial function is within 10% of the actual result, then the K-M variational principle gives the result to better than 1%. We have generalized the results of Kay for n-poles in such a way that practical applications are possible, e.g. to the ionosphere. To test the method we are in the process of studying the 4- and 10-pole cases before treating the 100-pole case.
