  1. Then we deal with the relative fluctuations as following : take relative fluctuations from small to big and take them as abscissa, the corresponding vertical is the total number that relative fluctuations equal to or bigger than the abscissa

    於是，我們對相對起伏做了一個處理：把它們按大小排列作為橫坐標，相應的縱坐標是不比橫坐標小的所有相對起伏的總數目。
  2. For example, the minimum relative fluctuation corresponds to the total number of all relative fluctuations, the maximum relative fluctuation corresponds to the number of itself

    比如，最小的相對起伏對應的縱坐標是所有相對起伏的總數目。最大的相對起伏對應的縱坐標是最大的相對起伏的數目。
  3. When the radar is narrow band, radar target is studies as a point target. target and clutter are modeled as having a zero - mean complex gaussian probability density function ( pdf ). target is assumed as slowly - fluctuant

    窄帶條件下，雷達目標可以看作是一個點目標，假設目標和雜波都服從零均值的復高斯分佈，目標為慢起伏。
  4. Based on the current helicopter operation at home and abroad on transmission line and its technical development trend, the paper has carried on research and demonstration on feasibility to apply helicopter in cruising inspection of yang - huai 500kv transmission line from various aspects as its significance, necessity, selection of operating management mode and technical working plan as well as its rationalization economically etc. applying helicopter to operate on power transmission has been tendency of the world power industry. on using helicopter to cruise, inspect and maintain the yang - huai 500kv transmission line, the first objective is to insist on flying safety. two steps should be taken seperately for short term and long term objective. first, to rent helicopters and then, to buy them

    採用直升機進行電力作業已經成為世界電力工業的潮流，應用直升機巡視和維護500千伏陽淮線，應堅持把安全飛行作為首要目標，宜分近期和遠期兩個目標分階段實施，先租機，再購機；直升機的選型，主要從安全性和經濟性兩方面考慮，在起步階段租賃bo - 105c直升機；要根據作業項目和方法選擇機載儀器設備；用直升機進行輸電線路巡檢，能極大地提高勞動生產率，具有明顯的經濟效益，並將提高我國直升機運用水平，促進我國通用航空事業的發展，從而帶動相關行業的發展。
  5. A method and hardware realization of detecting point target in strong background

    強背景大起伏條件下點目標雙尺度濾波檢測演算法
  6. The text compares experiment data with the selected theory direction fig and modifies the equal value and standard difference of each segment i n the se i ected wave w i dth d i r ect i on f i g by us i ng the re i at i ve i y between the statistical equal value and standard difference, then makes use of the controls the correlation time to real ize the signal undulate

    通過實驗數據與選定的理論方向圖的對比分析，利用統計出的均值和標準差的相對量，對給定波束寬度的方向圖每段的均值和標準差進行修正。然後利用相關特性，通過控制相關時間，以達到能夠控制信號起伏的目的。
  7. The way reduces the error. this paper also particularizes the prime parameter of the echo - - radar cross section ( rcs ) which is influenced by many factors. considering the fluctuation of rcs and the modulation by the radar antenna, the paper contains both slow and quick fluctuating targets

    兩種回波的模擬數據表明：模擬結果與理論模型的結論符合很好，能夠滿足運動目標回波幅度分佈特性的要求；並且在多數情況下，雷達探測到的目標都是慢起伏目標。
  8. To simulate return accurately, we set several models as follows : target radar cross section ( rcs ) model, target antenna modulating model, target wave modulating model, noise model, clutter amplitude distributed model and power spectrum distributed model. each of these models has been analyzed and simulated

    分別建立了目標截面積起伏模型、目標天線方向圖調制模型、目標波形調制模型、噪聲模型、雜波幅度分佈和功率譜分佈模型，對每種模型的建立進行了分析和模擬。
