  1. 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。
