Abstract: The applicability of several methods for processing experimental signals of local magnetic probes is analyzed for the purpose of determining the poloidal mode number m of MHD perturbations in plasma of tokamak with noncircular cross-section. These methods are the two-dimensional Fourier transform, the -Hilbert transform method, the method of singular value decomposition, and the method of phase matrices. The methods listed were applied under conditions of the D-shaped cross-section of the T-15MD tokamak vacuum vessel. They showed good results in determining the poloidal wave numbers of MHD perturbations for both synthetic and experimental signals of local magnetic probes. The results of processing the experimental data from local magnetic probes were in good agreement with the data of soft X-ray diagnostics of the T‑15MD tokamak. [ABSTRACT FROM AUTHOR]
