摘要
为提高制导武器在目标区域的生存能力,增大对目标的杀伤威力,以及实际战术应用的需要,需要武器按期望的方位角、俯冲角对目标实施攻击,因此提出了带有碰撞角约束的导引问题。针对此问题,借鉴TV-BPN的基本思想,在三维空间中重新设计偏置项,来同时约束俯仰与偏航碰撞角,提出了带有碰撞角约束的三维纯比例导引律(3DPPNGL/IAC)。并对3DPPNGL/IAC下的理想弹道进行了数字仿真,结果证明,在能捕捉到目标的同时,也能够对碰撞俯仰角、偏航角同时进行控制。
For improving the survivability of the guided weapons in target district, aggrandizing its damaging power to target, and to satisfy the demand of the actual military tactics, the guided weapon must attack targets in the desired impact angle, thus the problem of homing guidance with impact angle constraints is put forward. Aiming at this problem, by using the basic thought of the TV-BPN and redesigning the biased item in the 3D space, the authors presented the three-dimensional Pure Proportional Navigation Guidance Law with Impact Angle Constraints （3DPPNGL/IAC） in order to realizing constraints of impact angle. The numerical simulation of ideal trajectory proved that impact angle of both pitching and yawing could be controlled at the time of target could be caught.
