The master dissertation introduces passive correlative orientation system and base theory in signal dispose briefly in the first place. the system takes tv sound fm signal from tv satation signal. the power rate of tv station signal to sound signal is ten to one. in the case of submerged by mussy weave and machine ' s hot noise, dispersed target signal is feeble
系統採用電臺的電視伴音調頻信號，其中電臺信號與伴音信號功率之比基本為10 ： 1 ，並且目標散射信號較弱，一般情況下淹沒在雜波和機器熱噪聲之下，採用常規的脈沖檢測方法很難對遠距離的目標進行檢測，而以電臺直達信號作為參考與目標回波信號進行相關檢測；系統中信號的相關處理會產生旁瓣，而強目標的旁瓣會影響附近的弱目標檢測。In the light of the pulse width of the radar wave, this paper deals with the difference and the relationship between the vertical resolution and the transverse resolution of the ground - penetrating radar, indicates the influence of the noise upon the resolution and, with practical examples, points out that the digital handling of the signal can greatly improve the resolution of the radar
摘要從雷達波脈沖寬度出發，闡述垂直解析度與橫向解析度的區別和相互關系，並同時指出噪音對解析度的影響，用實例說明訊號的數字處理能大大的改善解析度。Melp vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional lpc vocoders, and add a jitter voicing state to overcome the tonal noise. parameters " interpolation, adaptive spectrum enhancement and pulse dispersion also are adopted to improve the continuity. the synthetic speech of melp vocoders sound much more natural and perceivable than the traditional vocoders "
Melp聲碼器採用混合脈沖和噪聲激勵解決了經典lpc的嗡嗡聲的問題；引入了抖動濁音狀態以克服音調噪聲；利用參數插值、脈沖散布和自適應譜增強等措施提高合成語音的自然度和可懂度；此外還採用了多帶激勵，使其具有了比較強的抗背景噪聲的性能。We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability
針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高A serial generalized morphological filter with multi - structural element is used suppression white gaussian noise or pulse noise embedded in the speech signal. the paper compares morphological speech enhancement algorithm with classical approach on the feature of speech in the frequency domain and time domain
本文針對形態學在數字語音信號增強中的應用演算法研究，採用多結構元素的廣義形態濾波器，主要用於對被高斯白噪聲或正負脈沖噪聲污染的語音信號的濾波增強，深入研究形態學濾波的語音增強演算法在語音時域、頻域對語音特徵參數的影響。Acoustics - impulse sound propagation for environmental noise assessment
