The contribution of single and multiple scattering to the spatiotemporal structure of radiation is estimated in the region of predominantly small-angle scattering (the optical thickness τ=1-20, zone near the axis). The broadening and exponential decay of the amplitude of the pulses as a function of the depth are investigated for different angles of observation. The effect of the angular aperture of the detector on the measurement of the width and energy of the pulse is estimated.
