crossing target
解釋
側行目標-
This design has distinctive technical features as follows : 1. applied multi - sensor construction. well - calculated distance and crossing angles between sensors aiming at a same target makes it possible to acquire more accurate back waves than single sensor construction
採用多探頭結構，多個探頭之間相互之間有一定距離和交織發射角度，對準同一個被測物體的反射面，可使檢測范圍內的每一個固定點上反射面的可測方位個數較單探頭有所增加，可大大降低回波漏檢率； 2 -
As a result the relatively reasonable basic data is designed and mathematics model on the firing effectiveness is established. then the c language program is used to solve the model and reasonable data index and relative theory on the basis of the large number of the simulation computation of the set target are obtained. the paper creatively puts forward the theory of the ship - borne artillery terminal guided projectile system and establishes the mathematics model to evaluate its firing efficiency, and creatively discusses the use of the terminal guidance system in the sea - crossing and island - landing battle, providing a theory basis for the future military struggle against taiwan
本文的研究針對末制導炮彈這種新型的精確制導武器系統的特點，以炮兵射擊理論為基礎，以現代戰場上重要的點目標和集群裝甲目標為研究對象，設定了比較合理的基礎數據；建立了射擊效能的數學模型；採用統計試驗法，運用c語言設計計算程序對模型進行求解；對設定的重要目標，進行了大量的模擬計算分析，得出了比較合理的數值指標和相關結論；對其作戰應用進行了探討性研究，創造性地提出了船載炮發射末制導炮彈武器系統的新技術，建立了評定其射擊效率的數學模型；創造性地探討了末制導炮彈武器系統在渡海登島作戰中的應用，為未來戰場上我精確制導武器的使用，做好對臺軍事斗爭準備提供了理論依據。 -
In order to limit the sensor numbers of the crossing location association method in high clutter or target density environment, a generalized likelihood ratio approach to eliminating ghosts is given. the approach is based on the fact that the sound intensity distribution of the same target is identical
為了防止當目標密度或雜波密度較大時，交叉定位融合需要傳感器過多，根據同一目標的聲壓分佈一定的特點，設計了一種消除交叉定位中虛假目標的廣義似然比檢驗法。 -
As to the software, it realized feature extraction and target identification from the seismic signals of representative moving targets using the zero - crossing method in time domain
軟體採用時域上的過零演算法對典型地面運動目標（如車輛、人員）的地震動信號進行特徵提取，目標識別。 -
In 1999, in light of the heavy transport demand at lo wu, government has approved the sheung shui to lok ma chau spur line, an extension of the east rail to form a second boundary crossing for rail passengers at lok ma chau with target completion by 2007
1999年，鑒于羅湖的客運需求十分殷切，政府已原則上批準興建上水至落馬洲支線，並會連接東鐵以成為落馬洲第二條跨界客運支線。這條支線預定於2007年建成。
