  1. The claim has been made upon the results that the wmt method should be used in the area near the vertical, while the phase difference method in slant beams and a rule has been given to select among those two methods according to the " effect value " on condition the depth is known for the consideration of improving the measurement precision, this paper studies the factors which affect the toa measurements, and three expressions of precision has been introduced as to applications of phase difference method, this paper introduces an automatic hunting method based on amplitude power to get the range of echo arrival

    採用方差分析的方法，使用重復海試數據對wmt法和相位差法的優劣進行了分析，指出了垂直附近應該使用wmt法，而傾斜波束應該使用相位差法；給出了在深度真實值已知前提下wmt法和相位差法使用的判決準則，即根據效應值的大小來選擇。本文從提高測量精度角度出發，分析並驗證了影響toa測量精度的因素；給出了三種精度表示。在應用相位差法時，引入了一種基於幅度能量的區間自動搜索方法；實驗表明該方法能很好地確定回波到達的大概時間范圍。
