We studied the degradation of the source pulse form in long-range propagation of low-frequency sound in the sound fixing and ranging (SOFAR) channel in the ocean. We made the numerical simulation of the source pulse propagation with changing the parameters of the simulation; carrier frequency, source pulse width, and propagation range. In long-range propagation such as 1000 km, 2000 km and 3000 km, there are a limited number of combination of the frequency and the pulse width for minimizing the consequent pulse degradation. These results are applicable to the design of the actual ocean propagation experiment itself and also of sound source equipment for the experiments.
