Pulsars and some quasars are so very bright that the conventional explanation for radioastronomical emission from other sources either does not apply to them, or presents unsolved problems. We see (in radio waves) these sources through the interstellar medium which acts like a wrinkled pane of glass in distorting the image. New scientific ideas and methodologies are proposed here and will be explored in the project, with the objective to understand these sources and to extract information on their propreties and those of the interstellar medium.

脉冲星和一些类星体是如此的明亮，以至于对其他来源的射电天文辐射的传统解释要么不适用于它们，要么提出了未解决的问题。我们（在无线电波中）通过星际介质看到这些源，星际介质就像一块起皱的玻璃，扭曲了图像。新的科学思想和方法在这里提出，并将在该项目中进行探索，目的是了解这些来源，并提取有关其特性和星际介质特性的信息。
