目視和音響全向無線電信標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。Visual - aural radio range
目視和音響無線電信標The exportation resistance of a device work device with what link after loading the resistance s the certain connections for should satisfying, in order to prevent mount to load the appearance produce the obvious influence. with each other connect to say to electronics equipments, for example after signal connect the enlarger, ex - class to connect class, only behind first - degree importation resistance before larger than first - degree exportation resistance 5 - 10 times are above, can think the resistance to match good ; connect the box come saying, electronics tube the machine should choose to use with for the enlarger its output to carry the mark to call the resistance the box for, but transistor enlarger then have noing this restrict, can take officing why resistance of equal or approximate box
一件器材的輸出阻抗和所連接的負載阻抗之間所應滿足的某種關系,以免接上負載后對器材本身的工作狀態產生明顯的影響。對電子設備互連來說,例如信號源連放大器,前級連后級,只要后一級的輸入阻抗大於前一級的輸出阻抗5 - 10倍以上,就可認為阻抗匹配良好對于放大器連接音箱來說,電子管機應選用與其輸出端標稱阻抗相等或接近的音箱,而晶體管放大器則無此限制,可以接任何阻抗的音箱。Vhf rotation talking beacon
甚高頻旋轉音響無線電信標In recent years, some new concepts of information security have been proposed, especially in the application of intellectual property right protection, copyright protection and tamper - proofing. information hiding and digital watermarking are new measures of digital media protection, which are processes of embedding hidden messages within digital media such as text, images, video and audio. the hidden messages could be copyright information, user distributor identification number, company logo, personal signature, control bits, or any information considered useful for a specific application
信息隱藏與數字水印技術就是一種新的數字媒體保護措施,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖像、語音、視頻及文本文件等各種數字媒體中,以達到標識、注釋及版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且具有特定的恢復方法,此信息對非法接收者應該是不可見、不可察覺的。This paper introduces the present situation of informatic and characteristic construction along with precious sound material rescues and conservation of jiangsu province each rank broadcasting stations ' sound material management, points out their problems in service communication, management standardization, service development, so as to supply the reference in the interest of improving work
摘要論文介紹了江蘇省各級廣播電臺音響資料管理工作中信息化建設、特色化建設以及珍貴音響資料搶救和保存等方面的現狀,指出其在業務信息溝通、管理標準化、服務開發等方面存在一定問題,旨在為改進工作提供參考。The iso / mpeg - audio layer iii digital audio compression scheme is the most powerful of the three audio compression algorithms standardized in iso / mpeg dis - 111 72. even at very low bit - rate of only 64kb / s, layer iii is one of the most excellent compression tools for applications such as real - time network radio and high fidelity music. this paper describes a study on algorithm simulation of mpeg / audio compression layer iii
Mpeg / audiolayer提供了iso / mpegdis - 11172標準的三個音頻壓縮方案中最強的壓縮能力,即使工作於64kbps ,仍能保證高品質的音響效果,是需要以低碼率傳送數字高保真音頻信號的應用領域的理想工具。Visual - aural range
