In this thesis, based on pershing ii surface to surface missile, a new kind of ballistic missile was designed with an additional rocket engine, which can be ignited twice. firstly, aerodynamic computational models of missile body and warhead which reentry with supersonic are built according to the task requirements ; secondly, the propulsion system model of missile is built whose first two stages are solid rocket engines and the third stage is liquid - solid combined rocket engine. the nozzle and the shape of the engine are designed to meet the needs of the populsion project ; thirdly, the trajectory model of the mass point is built and a wavy trajectory is designed & optimized ; finally, the ability of a missile ' s breaking through defence is analyzed
以美國潘興導彈為原型，增加可兩次點火的末級發動機，改裝成具有跳躍能力的地地彈道導彈；首先，根據任務需求，建立了導彈的氣動模型，並建立了彈頭再入時高超聲速氣動模型；其次，建立了導彈推進系統模型，前兩級採用了固體火箭發動機，第三級採用了固?液組合火箭發動機，並在總體方案要求下，對發動機噴管和外形進行了設計；第三部分，建立了導彈質點彈道模型，設計了一條跳躍式彈道，並對跳躍式彈道進行了優化設計；最後，對導彈進行了突防能力分析，從分析的結果可以看出，跳躍式彈道的突防能力比常規的拋物線彈道要強。 -

Aimmed to retard the response of ballistic missile defence system, the wavy trajectory with three crests is designed in this thesis to replace traditional parabola one. this kind of trajectory make anti - defence system have lots of difficulties to detect and compute the track and destination of ballistic missiles before reentry. so, applying the wavy trajectory can greatly improve the anti - defence ability of ballistic missiles
從延緩導彈防禦系統的早期預警時間著手，將傳統彈道導彈的拋物線彈道中段設計成有多個波峰的跳躍式彈道，使得探測系統在導彈再入大氣層之前，很難準確探測和計算導彈的落點，使得防禦系統防不勝防，從而大大地提高了彈道導彈的突防能力。 -

Then on the base of the computer model, the standard reentry trajectory guidance law is studied, and an approach to obtain the guidance coefficients by modifying the initial value through feedback bias repeatedly is put forward. simulations have proved the feasibility of the method
在這個基礎上，本文對飛船再入標準軌道制導方法進行了研究，提出了一種利用制導參數偏差迭代求解反饋增益系數的方法，並通過大量模擬驗證了此方法的可行性。
