摘要
本文利用傅里叶变换解卷积积分的方法,分析了1990年5月21日北京天文台2840MHz和2640MHz的射电爆发资料,分别求出了它们的激励函数.从激励函数曲线图中明显看出:激励函数曲线与观测曲线相比明显变窄,并且复原了被传输过程所平滑的精细结构.
In this paper, a method of convolution, which is based on Fourier transform techniques,, has been described. The exciter functions of the radio bursts observed on May 21, 1990 at 2840 MHz and 2640 MHz have been obtained by means of this method. It can be seen from the figures that the exciter functions of the radio bursts are very narrow and steep in comparison with the observed time profiles and contain some small peaks which are rounded out in observation.
