boresight 解釋
瞄準線
  1. For quick truning to target of air - to - air missile ( aam ) for short range dogfight in large off - boresight it is necessary to study the agile turn control law

    摘要為了使近距格鬥空空導彈在大離軸角發射時能快速地轉向目標,需要研究快速轉彎控制律。
  2. Many high - power microwave ( hpm ) sources utilize an azimuthally symmetric output mode such as the tm 01 circular waveguide or the coaxial tem mode as output mode. if radiated directly these azimuthally symmetric modes will generate a doughnut - shaped pattern, with a null on boresight

    許多高功率微波源產生的微波模式都是圓波導軸對稱模式,由於其輸出埠的口徑場分佈具有圓對稱性,將導致軸向為零的環狀遠場方向圖。
  3. Boresight fixture assembly

    校靶裝置
  4. Beam riding systems use a target tracker whose purpose is to maintain the antenna boresight pointing at the centre of the reflecting area of the target.

    波束制導系統使用一個目標跟蹤裝置,它的目的是保持天線視軸指向目標反射的中心。
  5. To ensure the reliability of tracking the target, signal attenuation and boresight error must be predicted accurately

    要保證導彈跟蹤目標的準確性,必須預測在給定掃描角下的信號衰減和瞄準誤差。
  6. Based on unsymmetrical heat environment, boresight error, boresight error slope and transmission coefficient of a specific shape radome have been calculated with indirect ray method

    在不對稱熱環境的基礎上,採用間接射線法計算天線罩瞄準誤差、瞄準誤差斜率及功率傳輸系數。
  7. Beam deflection produces boresight error ( bse ) which is defined as angle shift between viewing direction and true direction. boresight error slope ( bses ) is defined as the ratio of angle shift to the tracing angle of the antenna

    波束偏移的主要後果是產生瞄準誤差,使目標的視在位置與真實位置有一個角度差,這個角度差就是天線罩的瞄準誤差。
  8. For missile, either strategical or tractical, the most important thing is to attack the target accurately. this depends upon the accurate location of the larget by the missile radar. for protecting radar antenna from external environment and for air - dynamical requirement, a radome is used to enclose the antenna. but the radome interferes in the orientation of the antenna, degradaties its perfor - mance, decreases the power reaching the target, and most importantly, it produces so called boresight error ( bse ) that is, makes the antenna shows a slightly different direction of the target from its true direction, the boresight error is define as the angle shifted, and the boresight error slope ( bses ) is defined as the ratio of angle shift to the tracing angle of the radar antenna. to predict the boresight error and boresight error slope is an unavoiding chief task in designing radome and in its operation

    在戰略和戰術雷達制導導彈中,一項重要的工作就是對目標的準確跟蹤,這取決于導彈雷達對目標的準確定位。為了保護雷達天線不受外界環境的影響,天線罩被應用進來,但天線罩在保護天線不受外界惡劣環境影響的同時對天線電磁輻射產生某些干擾,使天線的電氣性能降低,影響天線的功率傳輸,更重要的是產生瞄準誤差。它使目標的視在位置與真實位置有一個角度差,這個角度差就是天線罩的瞄準誤差。
  9. Optical axes boresight instrument for multispectral optical system

    多光譜光學系統光軸平行性組合測試裝置
  10. Boresight misalignment calibration of integrated dgps imu system

    系統視準軸誤差檢校
  11. The previous discussion addressed the theory required to compute the relative phase shift between adjacent radiating elements in order to position the beam of an array - type antenna to a specific angle off of the antenna boresight axis

    前面的討論中給出了計算使陣列天線的波束相對天線視軸線偏移一個給定角度所需的相鄰單元間相對相移的理論。
  12. If the reference element has a phase of zero, compute the phase applied to element five when the beam is scanned 40o above the boresight axis

    如果參考單元的相位是零,計算第五單元當掃描視軸線以上40度的相位。
  13. Similarly, to position the beam below the boresight axis requires the use of a negative angle. this yields a negative and equation ( 7 - 4 ) again yields the applied phase of each element

    同樣的,要使波束低於視軸線要求負的角度。增量就是負的,式( 7 - 4 )仍可用於計算每個單元的增量。
  14. Based on the simulation results, a cobra antenna constituted by four reflectors is designed, the antenna produces a radiation pattern with a boresight peak, and the antenna gain reachs to 28. 4db

    通過數值模擬,設計了一種由四塊反射面組成的cobra天線,天線在軸向上輻射場最強,增益達到28 . 4db 。
  15. Research and development efforts have been underway for several years to explore a novel antenna concept that can directly accept microwave energy in an azimuthally symmetric mode, with a boresight peak

    本文從理論推導、數值模擬等方面研究了后兩類天線,即可以直接輻射軸對稱模式高功率微波的天線- vlasov天線和cobra天線。
  16. Often, mode conversion techniques are used to change the undesirable mode to one that results in a radiation pattern with a boresight peak such as circular te1 1 or rectangular te 01 mode

    因此研究軸對稱模式的天線輻射技術具有重要意義。輻射天線的工程設計方案通常有三種:模式轉換器+普通喇叭、 vlasov天線和cobra ( coaxialbeam - roatatingantenna )天線。
