This paper gives a brief account of the causes of multipath delay differences in the troposcatter channels and their impact on the scattering communications. The formulas for calculating the multipath delay differences are deduced, and the frequency correlation in the scattering channels and Frequency correlation coefficient test method, and from the relationship between multipath delay difference and the frequency correlation coefficient, the method of testing the multipath delay difference, but also cited the actual circuit test results.
