  4. The results show that of the resolution of the directional distribution is higher the mbdm than the mmlm and while of the resolution of the reflection coefficient higher the mmlm than the mbdm. the two methods are sensitive to the array disposal of wave gauges and the resolution power of t he analyzing results by the polygon array is better, while the linear array worse. the wave gauge number of array and the distance between the array and the reflector can influence strongly the resolution power of the analyzing results

    結果表明，對于波浪方向分佈的分析， mbdm的分辨力高於mmlm ，對于反射系數方向分佈的估算， mmlm優于mbdm ；儀器陣列的布置、儀器個數以及陣列與反射面的最近距離對兩種方法分析結果的分辨力影響較大； mmlm的收斂速度快于mbdm ，計算的穩定性優于mbdm ； mbdm的分辨力受超參數選擇的影響。
