Abstract: A novel angle-constrained guidance method based on proportional navigation with the virtual velocity of the target is proposed. This method features simplicity without the need for estimating time-to-go or target acceleration information. By introducing a virtual velocity in the desired direction relative to the true target, negative feedback on the line-of-sight angle is established, ensuring the satisfaction of the terminal heading angle constraint. The dynamics of the guidance command with varying parameters are analyzed in a linear engagement scenario, specifically involving a low-speed, non-maneuvering target. Additionally, two parameter configuration approaches are proposed for terminal command convergence and optimization, clarifying their connection with previous work. Comparative numerical simulations verified the effectiveness of the proposed method in satisfying angle constraints and demonstrated its robustness against maneuvering targets.
