海底混響 的英文怎麼說
中文拼音 [hǎidehúnxiǎng]
海底混響
英文
sea bottom reverberation-
Sea-bottom reverberations would extrapolate back-wards in time to a zero member.
海底交混響就是按時間外推到一種時間零值的。Echo extraction from bottom reverberation based on chaos
基於混沌理論的海底混響中目標回波提取Lt is obvious that the decaying rule of average reverberation intensity is affected by scattering coefficient of sea floor, sound speed profile, inclination of bottom etc. the sea floor scattering function is the most importan factor to the intensity decaying rule
結果表明:海底散射方向性指數因子、海水聲速梯度、海底傾斜角等對海洋混響平均強度的衰減皆有影響。海底散射方向性指數因子對其影響最大,即適當選取海底散射模型是淺海近程混響建模的首要因素。First, the formula for average intensity of ocean reverberation is deduced on the basis of ray theon " for monostatic case, then it is proved by computer simulation and experiment data
本文首先從分層介質的射線理論出發導出傾斜海底收發合置淺海近程海洋混響平均強度的近似表達式,並對其進行數值分析與實驗驗證。The sound speed profile is another important factor, the bigger sound speed gradient, the faster reverberation intensity decay and the other factor to the reverberation intensity decaying is sea floor inclination, the greater the slope angle, the slower reverberation intensity decav
其次,對混響強度影響的第二大因素是聲速梯度,聲速梯度越大,混響強度衰減越快。第三,海底傾斜角也會影響海洋混響的衰減,海底傾斜角越大,混響平均強度衰減越慢。分享友人
