      摘要:
      為了研究水下目標聲散射相位特性,本文基于經典Rayleigh簡正級數解的解析方法和有限元數值方法對球體目標365英超体育投注,如剛性球365英超体育投注、彈性球和球殼的散射聲場進行計算。結果表明:剛性球在ka > 2π時相位隨頻率呈現接近線性變化365英超体育投注;彈性球在彈性波共振頻率處出現相位跳變現象;不同材料、殼厚的球殼相頻特性有很大的差異365英超体育投注。最后通過單層球殼水池聲散射實驗,采用全相位法獲取了其聲散射相位特性,在20~40 kHz頻段與理論預報結果相比吻合較好365英超体育投注。研究結果為利用水下目標聲散射相位信息進行目標識別和主動聲隱身提供理論支撐365英超体育投注。
