A Hybrid Guidance Law for a Strapdown Seeker to Maintain Lock-on Conditions against High Speed Targets

Abstract: -This paper proposes a new guidance law, which considers the Field of View (FOV) of the seeker when a missile has a strapdown seeker mounted instead of a gimbal seeker. When a strapdown seeker, which has a narrow FOV, is used for tracking a target, the FOV of the seeker is an important consideration for guidance performance metrics such as miss distance. We propose a new guidance law called hybrid guidance (HG) to address the shortcomings of conventional guidance laws such as proportional navigation guidance (… Show more

“…Xing et al 9 designed a FOV angle control guidance law through minimizing the velocity component perpendicular to the line-of-sight (LOS) to reduce the seeker look angle. Lee et al 10 derived a sliding mode guidance law to keep the look angle within the FOV angle by employing a Lyapunov-like function with a sliding mode control methodology. Sang and Tahk 11 proposed a guidance law switching logic between the original guidance law and the constant look angle guidance law using Lyapunov theory.…”

“…With this approach, the stability regions of the parasite loop, involving the strapdown homing seeker, were analyzed in several studies [5][6][7][8]. As the second research direction, some efforts have also been made to devise new homing guidance laws, corresponding terminal homing guidance loops [9][10][11], and guidance filters for the strapdown seeker [12][13][14].…”
