A guidance law for avoiding specific approach angles against maneuvering targets

The article of record as published may be located at http://dx.doi.org/10.1109/CDC.2016.77988972016 IEEE 55th Conference on Decision and Control (CDC)This paper investigates an augmented pure proportional navigation-based guidance strategy, which expands upon the need for precise control of the terminal approach and/or impact angle of an interceptor by also accounting for the maneuvering target’s ability to counter attack, e.g., in air-to-air combat. Specifically, an anticipatory modulation of the augmentation parameter is presented and analyzed, which addresses the objective of ensuring that the pursuer avoids any approaches that would place it within the evader’s own sights. Simulation results are developed and presented to support the theoretical findings
