    本文在分析借鑒國外資料的基礎上,研究了利用fft波束形成技術來增加波束形成數目,並應用bdi演算法和分裂孔徑相關法來完成對海底回波信號的時間和方向的聯合估計等相關技術對海試數據進行處理。
  2. Bdi bearing deviation indicator

    航向偏差指示器
  3. Bearing deviation indicator

    航向偏差指示器
  4. Top - directly as a basis and foundation of the bearing surface as the top - embedded steel bearings or bearing surface, the supporting surface, the anchor bolt ( anchor ) position should be consistent with the allowable deviation of norms

    基礎頂面直接作為柱的支承面和基礎頂面預埋鋼板或支座作為柱支承面時,其支承面、地腳螺栓(錨栓)位置的允許偏差應符合規范的規定。
  5. The results of the experiment show that the peak value, rms, standard deviation, crest factor, kurtosis value and impulse value of the vibration signals can distinguish between the normal and abnormal conditions of the ball bearing when the level of noise is low

    常用包絡解調技術對此類信號進行分析,但易受噪聲影響,使得齒輪或滾動軸承的故障特徵難以凸顯。本文從研究相關函數的特性入手,經理論證明,發現自相關函數並不改變調制信號的調制特徵,但具有顯著的降噪特點。
