PULSE BROADENING DUE TO MULTIPATH SCATTERING OF RADIO WAVES BY THE INTERSTELLAR MEDIUM

of Science. The formal solution to the problem of finding the pulse shape in the time domain received when an impulse is transmitted by a pulsating radio source and deflected at an arbitrary number of screens between the source and the observer is found. A Gaussian distribution of scattering angles is assumed at each scattering screen. The general solution is found for N-1 screens in the form of an integral over 2N-3 variables. This expression is integrated analytically for N=2 (single screen case). A Monte-Carlo technique is used to fin
