Definition

Because the fourth-stage burn pushes the interceptor away from the target point, Lambert guidance leads it to an offset aimpoint R_offset = R_T − ΔR to compensate for the position deviation caused by the burn, where ΔR is computed by integrating the burn duration with the rocket equation.

Application Value

位置偏移补偿through Lambert 制导引导至偏移瞄准点来补偿燃烧produce of 位置偏差, is 提high落点accuracy of important technology. In 弹道导弹和lunar着陆中has application.
