    在觀測坐標系中推導出確定天頂盲區理論范圍公式和滿足過天項跟蹤條件的關系式；在天文坐標系中以長春衛星觀測站（北緯43 . 9 ）作為計算基準，分別討論了方位、俯仰方向的角速度、角加速度等對天頂盲區的影響，在理論分析上為解決過天頂跟蹤問題打下了基礎。
  2. Second, by computing the trajectory of the missile and the method of analyzing cep, influences that the fighter ' s height, speed, pitch angle, the deflection angle between fighter and target, and the target moving characters make on the times of fighter attack and missile launch are deeply developed. third, by relating the motion of the missile and the fighter, the influences that fighter ' s dive angle and the deflection angle between fighter and target make on the attack field of the fighter are discussed in this paper when the fighter perform vertical and horizontal attack. criterion of attack effect is proposed focusing on attack time of the fighter, trajectory of the missile and destruction probability to the target

    本文主要完成了以下幾個方面的工作：對導彈可發射區和飛機可攻擊區進行建模，通過對導彈彈道的模擬計算，並運用典型的圓概率偏差精度分析方法，詳細討論了飛機實施攻擊時，飛機的飛行高度h 、速度v 、俯仰角、與目標的偏離角_ x及目標運動特性等對飛機攻擊時機和導彈發射時機的影響；因此，將飛機和導彈結合起來，詳細研究了飛機在垂直平面和水平平面內實施攻擊時，飛機俯沖角和與目標的偏離角_ x對飛機的攻擊范圍的影響；以飛機實施攻擊的時間t 、彈道特性和對目標的殺傷概率p來評判對地攻擊的效果；最後給出典型算例，通過對空地攻擊過程的模擬實現，對飛機飛行過載提出要求。
  3. To solve the problems caused by the varieties of the missile dynamics with the difference of flight height, velocity and attitude angle in modeling the missile, in this thesis, the theory of variable structure model reference adaptive control is used to design a pitch channel autopilot based on a longitudinal missile model, the status equation using the measurable parameters of load and angular rate is established, and the methodology to choosing the reference model is discussed also, and the performance of the controller is analyzed by means of simulation

    為了解決攔截彈氣動參數隨飛行高度、速度、姿態的不同，變化范圍大，控制系統難以準確建模的困難，基於縱向平面攔截彈模型，採用模型參考變結構控制理論設計了俯仰通道姿控復合控制系統，以可測量變量過載和角速度作為狀態量建立了系統的狀態方程，討論了參考模型的選擇方法，並對系統的性能作了模擬分析。
  4. Linear array can only provide an azimuth scan ranging from 0 to 180 degree, while circular array from 0 to 360. by means of recurring moving array excitation, circular array controls the beams ’ orientation simply and neatly, creating a perfect pattern in azimuth and an ideal pattern in pitch
