摘要
从色散原理出发,将消色散问题反演转化为解积分方程的问题,并在消色散接收机原理的启发下,将积分方程离散化为方程组,并采用分段反演的方法对其求解。求解过程以及对该方法所作的检验表明,在理想化条件下,反演结果与预先给定的理论曲线吻合得很好。
This paper reviews the dispersion effect- prolongation and distortion- on the mean pulse of pulsars by interstellar free electrons and develops a mathematical method for its correction. Starting from the dispersion theory the problem of the dedispersion inversion is transformed into one of solving an integral equation. After discretization solution by sections is obtained. Under idealized conditions, the results of the inversion agree well with the present curve.
