摘要

To address the problem of hypersonic vehicle interception, taking the air-breathing hypersonic vehicle as the target of interception, this paper employs the concept of engagement geometry to theoretically provide the necessary conditions for the successful interception of hypersonic vehicles as well as constraints on the velocity-leading angle of hypersonic vehicle from the perspective of a small velocity ratio (the velocity of the interceptor is lower than that of the hypersonic vehicle) based on the interception posture. Then, it puts forward the mathematical expressions for the interception space of the interceptor for different maneuvering modes of the hypersonic vehicle, taking the true proportional guidance law as an example. Finally, by simulation experiments, it presents the interception space changing curves on the conditions of different velocity ratios and different maneuvering modes of hypersonic vehicles, and systematically analyses the conditions of intercepting hypersonic vehicles from a small velocity ratio perspective. This study can provide a fundamental theoretical basis for the mid-end guidance handover conditions and guidance law design for the subsequent interception of hypersonic vehicles.
