Rotation measure calculation algorithm for pulse radiation in decameter range

We propose a new method for the determination of the rotation measure (RM) for pulse sources in the decameter wavelength range. This method allows us to define RM with accuracy up to 10⁻⁴ [1–3], which had never been achieved in any known methods. The method is effective in the consideration of individual pulses, and allows us to determine RM along the pulse profile.
