摘要
借助于弱散射理论和模式拟合方法,单站行星际闪烁观测可以诊断太阳风速度,本文讨论了太阳风参数和射电源角尺度对闪烁谱的影响,以及太阳风速度的积分效应,结果表明,闪烁谱的特征是与视线上距太阳最近处的太阳风速度直接相关的。
By means of weak scattering theory and model-fitting method, single station IPS observation can be used to measure solar wind velocity. The effect of solar wind parameters and radio source angle scale on the IPS spectrum as well as the integration effect of solar wind velocity are discussed. It is showed that the feature of IPS spectrum correlate directly with solar wind velocity in the closest point fo the sun on the line of sight.
