提出了一种新的寻的制导法则，以期望的姿态角撞击目标。它是传统比例导航制导 (PNG) 定律的变体，其中包括补充时变偏差。拟议的指导法不需要估计剩余时间，并且形式更简单。还提供了实现指导目标的分析条件。仿真结果表明，所提出的制导律比之前的制导律具有更宽的发射包络线，并且即使针对机动目标也表现出良好的性能。
A new homing guidance law is proposed to impact a target with a desired attitude angle. It is a variation of the conventional proportional navigation guidance (PNG) law which includes a supplementary time-varying bias. The proposed guidance law does not require a time-to-go estimation and has a simpler form. Analytic conditions for fulfilling the guidance goal are also provided. Simulation results demonstrate that the proposed guidance law has wider launch envelopes than the previous one and shows a good performance even against a maneuvering target.
