The reasons focusing only on ray travel times are " noise tolerance could be enhanced and the sensitivity to the environment model mismatch may be reduced by neglecting amplitude information ; phase ambiguity is eliminated by employing the group delay of arriving wave packets ; travel times are pseudo - linear functions of sound speed profiles of the medium, and the perturbation of ray travel time is much smaller than sound pressure ' s
之所以選擇聲傳播時間的原因是：噪聲容限可以得到提高，並且傳播時間的計算可以不考慮聲壓的信息，從而降低了對環境模型失配的敏感性；相位的起伏也可通過到達包絡的群延時來消除；傳播時間是介質聲速分佈的偽線性函數並且傳播時間的起伏遠小於聲壓的起伏。 -
