Interstellar scattering causes broadening and distortion to the mean pulse
profiles and polarization position angle (PPA) curves, especially to the pulse
profiles observed at lower frequency. This paper has implemented a method to
recover the pulse profiles and the PPA curves of five pulsars which have
obvious scattered pulse profiles at lower frequency. It reports a simulation to
show the scattering and descattering of pulse profiles and PPA curves. As a
practical application, lower-frequency profiles and PPA curves of PSR 1356-60,
PSR 1831-03, PSR 1838+04, PSR 1859+03, PSR 1946+35 are obtained. It is found
that the original pulse profiles and PPA curves can be recovered.
