On the perturbation parameter of nonuniform fluctuating ionospheric plasma

A new version of the noncoherent method for estimating the signal/noise parameter beta(K) of the ionospheric signal (IS) is proposed. The comparative analysis is performed, and it is shown that the analytical (relative) accuracy of determination of beta(K) by the new method exceeds the accuracy of a widely used standard procedure by an order of magnitude and has the same order as the accuracy of the known coherent procedure.
