  4. 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。
  5. The expression of single photon acquisition probability is deduced from the fundamental - mode gaussian beam

    基於基模高斯光束,推導了單光子捕獲概率的表達式。
  6. Progress, though steady, has been slowly, due largely to difficulties inherent in attempts to characterize a random natural phenomenon in terms of a limited set of parameters. for many years, various non - gaussian probability distributions have been offered as models for the amplitude of sea clutter

    對海雜波的研究迄今已有50多年,但其實驗數據和理論遠不能令人滿意,還不可能對海面回波的電平(作為雷達參數和海面狀態參數的函數)做出高度準確的預測。
  7.
