摘要標志是一種可以表達一定含義,傳達明確信息,克服語言和文字上的障礙及表達困難的大眾傳播符號。Standards of digital tv broadcast has specified transmitting systems which are based on various medium such as satellite - oriented transmitting system ( dvb - s ), cable - oriented transmitting system ( dvb - c ), terrestrial - oriented transmitting system ( dvb - t ). different system adopts different methods of channel codec, modulation and demodulation, but for signal source block codec, only mpeg - 2 standard has been applied for all the systems. as a compression standard being specified in digital tv broadcast transmission, mpeg - 2 has been widely involved on compression occasion
對于數字電視信號的傳輸,數字電視廣播標準制定出基於多種媒質傳輸的傳輸系統,如衛星傳輸系統( dvb - s ) ,電纜電視傳輸系統( dvb - c ) ,地面廣播( dvb - t ) ,不同的傳輸系統制定不同的通道編碼和調制解調的方法,但是對于所有傳輸系統的信源編碼則一律採用mpeg - 2這一標準。The land clutter is useless signals for target detection caused by land terrain. the multipath effect is some kind of interference which is caused by wave reflection on terrain. the diffraction effect is the phenomenon of wave propagation into shadow region
地雜波是由地面散射引起的對目標探測無用的信號;多路徑是由電磁波在地面反射所引起的干涉;衍射則是電波繞射傳播到遮蔽區的現象。That is, modeling radar system with software, and then recurring the produce, transmission processing by computer. the core of res is modeling the scatter and transmission of radar echo signal and varied radar clutter signals
雷達模擬的核心是建立雷達目標回波信號及各種雜波信號散射、傳播特性的模型。雜波伴隨這雷達產生而產生,對于雷達的設計有著重要的影響。The former requires all the possible positions should be provided by the location model at first. then the real one will be selected by majority rule. different from the former, the later, utilizing a given position reference, intends to resolve ambiguities before solving positioning functions
前者要求解算出目標所有的模糊位置,然後由一系列判據舉手錶決確定真實位置;後者需要目標初始位置這一先驗信息,利用此信息可以唯一確定信號的傳播時延,從而實現無模糊定位。Through the analysis of the test data and the new development in the relevant literature, some more realistic models for sea - clutter and multipath propagation is concluded and the simulation is accomplished in the software. they provide the foundation for low - altitude radar target detection & tracking techniques research. in the second part, radar low - altitude target detection & parameters ( elevation - azimuth - range delay - doppler shift ) measure are studied
(海)雜波和目標信號的多徑傳播嚴重影響了雷達低空目標探測與跟蹤的性能,通過分析國內外的有關試驗數據和最新的研究進展,總結出比較接近實際的海雜波和多徑傳播模型,並在有關軟體中實現了海雜波與多徑傳播的模擬,為進一步研究各種低空目標探測與跟蹤測量演算法提供了保證。The third part pay more attention to elevation tracking with monopulse radar while the target is in the horizon region. multipath propagation seriously degrades the performance of elevation tracking and makes the radar unable to work properly
當目標處在這一區域時,信號的多徑傳播給俯仰角測量帶來很大誤差,使包括dmc雷達在內的許多雷達難以正常工作。Active underwater acoustic positioning / tracking systems locate target by measuring the range from object to receiving sensors. usually the target - receiver range can be got by the propagating time of a signal pulse. if this propagating time is larger than the pulse repetition period, it will mean that more than one signal pulse are on propagation
主動水聲跟蹤定位系統通過測量脈沖信號的傳播時延可以測得目標相對接收機的距離,當此傳播時延大於系統同步周期時,時延測量就會呈現不確定性,可能相差若干個重復周期,導致定位解多值,稱之距離模糊現象。分享友人
