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.

研究非热电磁等离子体发射光谱中快速扫频事件动力学的方法

我们开发了一种处理等离子体发射动态光谱的算法，这使得提取频率增加和减少的啁啾元素成为可能。该算法在一组实验数据上进行了测试，这些数据是通过研究开放磁阱中电子回旋共振放电的稀薄等离子体的发射光谱而获得的。对于信噪比超过 30 dB 的信号，该方法的效率接近 100%，对于信噪比为 20 dB 的信号，效率约为 50%。该方法可用于实验室和空间等离子体动态发射光谱的自动分析。
