Abstract
We developed an algorithm for processing of the dynamic spectra of plasma emission, which makes it possible to extract chirped elements with both increasing and decreasing frequencies. The algorithm was tested on a set of experimental data obtained by studying the emission spectra of the rarefied plasma of an electron cyclotron resonant discharge in an open magnetic trap. The efficiency of the method is close to 100% for signals with a signal-to-noise ratio of more than 30 dB and about 50% with a signal-to-noise ratio of 20 dB. This method can be used for automated analysis of dynamic emission spectra of both laboratory and space plasmas.
