A New Biased Proportional Navigation Guidance for Decelerating Targets

Abstract

This paper aims to suggest a new type of biased proportional navigation guidance (PNG) for a target that undergoes a considerable deceleration during a homing engagement. To this end, the exact collision course between the missile and the target is first determined. This condition is given by a function of the time-varying speed of the target until the interception. The above interception condition is relaxed by utilizing the concept of average speed. Finally, the proposed law is realized in a way of achieving that condition, using the idea of biased PNG. We discuss the characteristics and implementation issues of the proposed approach. We validate the performance of the proposed algorithm using numerical simulations. © 2022, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
