Pulse Guidance Method for Intercepting Maneuvering Target

This paper proposes a pulse guidance method suitable for intercepting maneuvering targets in the exoatmospheric region. First, to address the performance limitations of traditional proportional guidance in intercepting maneuvering targets, a sliding mode guidance law is designed based on first-order sliding mode control theory, and its stability is proven using Lyapunov theory. Next, by incorporating prior target estimation information, an engineering implementation approach for the guidance law is derived. Continuous guidance commands are directly applied to the exoatmospheric interceptor with pulse thrust characteristics, and a time-delay element is introduced to reduce energy consumption during the interception process. Finally, the proposed method is validated through high-precision interceptor models and various simulation scenarios. The results demonstrate that the proposed pulse guidance method achieves high interception accuracy for maneuvering targets.
