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。However, background noise and room reverberations in enclosure greatly degrade the effectiveness of acoustic source localization
但由於噪聲和混響的存在,使得現有語音定位演算法的定位精度較低。Average intensity is one of the physical parameters which are used to describe the oceanic reverberation and the researches about it had been carried out a long time before. but not thoroughly yet
平均強度是描述海洋混響的一個重要物理量,很早就有人對其衰減規律進行研究,但至今還沒有得到完滿的結果。Under the illumination remark of chaos, this thesis raises the idea of modeling oceanic reverberation as an observation of a nonlinear deterministic system by the dynamics. the purpose is getting a new look to the reverberation
根據這一思想,本文提出混響的非線性動力學建模,即非線性確定性建模,從而給出認識混響過程的另外一個全新的角度。The research results show that the target strength and reverberation of bistatic sonar are different from those of monostatic sonar
研究表明,在雙基地條件下,受雙基地幾何關系影響最大的是目標強度和混響。Then a new method by combining beamforming with gcc is presented to efficiently suppress the noise and reverberation. what is more, the improvement to gcc - phat algorithm is also developed, specifically usefulness to background noise and room reverberation elimination
2 )對延遲-相加波束形成的定位方法作了詳細推導,並針對該方法的缺點加以改進,使其在混響環境下也有較高的精度。The bistatic average intensity firstly rises wt time to a top point, then it goes down, and the decaying rule is close to the monostatic reverberation intensity ap ) j { jgj : 8kq @ f9tt & z decaying rule, but reverbefation intensity will be closely related to the relative site of the transducers
收發分置時的混響平均強度隨時間的變化先是增加,到一個極大值時再隨時間的變化而有規律地減小,其衰減規律與收發合置混響強度衰減規律一致,其強弱與接收水聽器所處位置有關。In this thesis, some useful rules for average reverberation intensity decaying are given basing on the work which have been done by other researchers
本文就是在前人工作的基礎上對淺海海洋混響平均強度衰減規律進行了一些有益的改進。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。The thermocline causes omittable effect on the intensity decaying speed. but the site of hydrophone affects the reverberation intensity when hydrophone lies upper than the thermocline, the reverberation intensity is greater than when there is no thermocline, and vice versa. at last, the average intensity of reverberation for bistatic case had been deduced
發射聲源與水聽器在聲速躍變層上方時,水聽器接收到的混響強度比無聲速梯度時接收到的混響強度大;發射聲源與水聽器在聲速躍變層下方時,水聽器接收到的混響強度比無聲速梯度時接收到的混響強度小。分享友人
