Abstract

Methods of wave analysis of time series are analyzed in detail, namely: two-spacecraft phase difference, beamforming, k-filtering, MSR (Multi-point Signal Resonator) technique. These multispacecraft methods allow to obtain a set of wave power peaks with different spatial scales at the same frequency, which is a significant advantage over the single-spacecraft approach due to existence a significant number of wave modes at the same frequency in space plasmas. The software implementation of these methods with their successful testing on artificial data is executed. The effectiveness of each method for detecting maxima in the power spectra of the magnetic field is demonstrated.
