A variable flow ducted rocket (VFDR) engine offers a broader operational envelope than ramjet engines, as well as higher energy efficiency and a more flexible thrust modulation capability than conventional solid-fuel rocket engines, making it well-suited for long-range air-to-air missile applications. For such missiles, appropriate mid-course guidance toward the predicted intercept point (PIP) is essential prior to seeker’s lock-on. However, due to the high maneuverability of aerial targets, the PIP may vary significantly over time, necessitating adaptive mid-course guidance strategies. As a preliminary investigation into this challenge, this study performs trajectory optimization for a VFDR missile considering radar field-of-view (FOV) constraints for data link communication between the fighter and the missile. The results indicate that radar FOV constraints can affect the optimal trajectory, particularly when the target is relatively close and at higher altitudes.
