利用SGR 1806-20的巨γ射线耀斑的舒曼共振记录,模拟和讨论了一种可能的效应。我们表明,白昼侧电离层修改是能够导致全球电磁共振的功率谱的突然减少。光谱的变化会随着时间的推移而逐渐消失,因此通常和规则的模式在几十分钟内就可以恢复。本文提出了信号声谱图在γ射线暴前后的信号处理中的应用,为γ射线暴的探测提供了一种新的方法。
A possible effect is modeled and discussed on the Schumann resonance records of the giant γ-ray flare from SGR 1806-20. We show that the dayside ionosphere modification is able to cause an abrupt reduction in the power spectra of global electromagnetic resonance. Spectral modifications fade in time, so that the usual and regular patterns are recovered in tens of minutes. An application of signal sonogram is suggested for the signal processing around the time of γ-ray burst, which would facilitate detection of the event.
