  In this paper the anomalous intense pulse of the PSR J0953+0755 was studied
in decametre wavelength range. For this pulse two scales of fine structure were
discovered. The long-scale structure consists of four components, where the
visible dispersion measures of even and odd components are different. The
obtained time-scale of the short fine structure is 1 ms. The difference in
visible dispersion measure can be caused by propagation of two normal modes of
the pulsar radiation and irregularities of electron concentration in the space
near the neutron star like upper layers of magnetosphere and pulsar wind.
