Hyperbola-Like Impact Angle Guidance Law with Reduced Look Angle Variation
摘要
This study proposed a homing and field-of-view limited guidance law that considers impact angle constraints. To address such constraints, the look angle profile is molded into a hyperbola-like curve, whose first-order derivative on the collision is zero. By assessing the correlation between the line-of-sight and look angle, the feasible terminal line-of-sight angle is attained by determining the single parameter in the designed guidance law. The solution of the single parameter involved in the reference profile can be obtained by a simple numerical routine. Numerical simulations are conducted to validate feasibility and effectiveness of the guidance law.
