incoherent signal 解釋
非相干信號
  • incoherent : adj. 支離破碎的，七零八落的，東扯西拉的；不連貫的，前後矛盾的；無條理的，不相干的。adv. -ly
  • signal : n 1 信號，暗號；信號器。2 動機，導火線 （for）。3 預兆，徵象。adj 1 暗號的，作信號用的。2 顯著的...
  1. Wavelet packet transform is used to improve the snr of the incoherent integral radar echo, and bispectrum algorithm is used for signal detection in this united detecting algorithm, based on the modeling for the through - wall radar echo

    在對穿墻雷達回波信號建模的基礎上，用聯合演算法將非相干累積后的回波信號經過小波包變換提高信噪比，再用雙譜演算法進行信號檢測。
  2. Advantages, disadvantages and limits of arm are thoroughly examined using signal processing methods. based on the above, incoherent and coherent two - point - source decoy methods and modified coherent two - point - source decoy methods to deflect arm are brought forward. arm ’ s homing heads are generally of mono - pulse structure, so coherent two - point - source ’ s interference resembles that to mono - pulse radar except that interference to radar belongs to far field scope, but interference to arm varies from far field to near field because relative distance drastically changes between the homing head and the two - point - source with missile ’ s homing head continually approaching the target

    Arm的導引頭一般為單脈沖體制，因此，相干兩點源對導引頭的干擾類同於對單脈沖雷達的干擾，不同的是:對雷達的干擾都是遠場，而導引頭隨著導彈不斷接近目標，兩點源與導引頭的相對位置發生劇烈變化，由遠場變化到近場;導引頭天線口面上的合成場也發生了大的變化，相位波前的畸變產生干擾，這就是相干兩點源誘偏的基本思想。
  3. In the broadband incoherent beamspace high resolution method, the outputs of mvdr beamformers are used to suppress the interference from outside the beam coverage region in each subband. computer simulation results show good performance at low signal to noise ratio ( snr )

    該方法克服了基於預成恆定束寬波束輸出的寬帶相干高分辨處理方法不能有效抑制波束區域之外強于擾的不足，模擬結果表明該方法在低信噪比具有良好的性能c
  4. The paper introduces the history of bbadcp, discriminates the different among pulse - incoherent system, pulse - coherent system and pulse - pulse coherent system, analyzes the characteristic of bbadcp " s signal and explains how bbadcp works by reasoning

    介紹了bbadcp的研究狀況，比較了幾種測流技術，分析了bbadcp的信號特性，仔細推理了bbadcp的工作原理。採用基帶模擬的方法建立了bbadcp的計算機模型。
  5. Two wedge interferometers are designed that the thickness of one is higher than the other. so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift, but the incident incoherent light only result in consistent intensity signal. through a differentiating amplifier, two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals. this method largely improves the system and the ability of detection. the spacing of line fringes is a function of incident laser wavelength, by analyzing, we can extract the wavelength of incident laser. the optical unit analyzing and results also simulated with matlab

    當背景光入射時，直接穿過干涉儀，僅發生強度的衰減，在兩個探測平面上產生幅度基本一致的灰度信號，通過差分放大器，相消為零，從而抑制了背景干擾。當激光信號入射，穿過干涉儀時受到調制，在探測平面上產生干涉條紋。通過所設計的存在平均厚度差的雙楔形干涉儀，兩路干涉條紋圖案出現相對移位：在兩個探測平面對應的位置上，一路出現亮紋，另一路出現暗紋。
