Abstract: Multi-aircraft cooperative guidance technology currently represents a research hotspot and crucial development direction in the field of precision guidance. This paper systematically elaborates research progress and developmental trends in multi-aircraft cooperative guidance technology. First, it conducts an in-depth analysis of recent domestic and international literature on related topics, performing cluster label optimization analysis and generating keyword clustering diagrams. Subsequently, based on the keyword clustering results, the research directions of multi-aircraft cooperative guidance technology are categorized into three distinct approaches: architecture optimization-based cooperative guidance, constraint-based cooperative guidance, and differential game-based cooperative guidance. Each research direction is comprehensively reviewed through inductive synthesis, with detailed summaries of their research frameworks and technical pathways. Finally, building upon current research trends in multi-aircraft cooperative guidance technology, three prospective development directions are identified: heterogeneous multi-aircraft cooperative guidance architectures, multi-mode composite cooperative guidance, and application of intelligent algorithms. These proposed directions establish a foundation for advancing future research in this field.
