The correction of regular dispersion distortions in wideband high-frequency radio channels leads to a significant increase in the band undistorted communication. The hardware implementation of correction is difficult because of radiophysics methods and mathematical models for the study of irregular stochastic dispersion distortion investigated nit well. In presented study mathematical models of wideband high-frequency radio channels impulse characteristics was developed and the influence of stochastic dispersion distortions on these was researched. Experimentally was shown that stochastic (irregular) dispersion can be described by a normal distribution with mean zero in the range 0-75 ms. As a result of computer simulation revealed that in the case of stochastic variance in its normal distribution with zero first moment and standard deviation more than 75 ms the regular structure was destroyed.
