| 摘要: |
| 针对全捷联空地导弹视场小、过载能力有限，对攻击目标具有一定角度约束的问题，提出了一种分段制导方案。该方案将攻击弹道分为滑翔段、落角约束段、截获调整段、末制导段和盲区段。滑翔段增加射程，落角约束段提前实现终端落角可控，截获调整段调整弹体姿态，使目标进入导引头视场区域内，为导引头截获目标创造条件，末制导段采用比例导引、姿态追踪的复合制导策略，以同时满足视场约束和精确打击要求。仿真结果表明，采用该弹道分段规划方案可以解决多约束下全捷联空地导弹攻击地面时敏目标的工程化应用问题。 |

| Abstract: |
| The air-to-ground missile with strapdown seeker may have the problems, including small field of view(FOV), limited overload, and fall angle constraint. To solve the above mentioned problem, a phased guidance scheme is proposed. In this scheme, the attack trajectory is divided into the following six stages, including glided stage, fall angle constraint stage, target acquisition and adjustment stage, terminal guidance stage and blind zone stage. The glided stage is designed to increase range, the terminal fall angle is attained ahead of time at fall angle constraint stage. The aim of target acquisition and adjustment stage is to adjust the missile attitude, so that the target will fall within the FOV of the seeker. It creates good condition to capture the target for strapdown seeker. In the terminal stage, the guidance law of proportional navigation and attitude track are used to fit the needs of FOV constraint and attack accuracy. The simulation result shows that the project trajectory can solve the application of attacking moving targets for air-to-ground missile with strapdown seeker under multi constraints. |
