Modern combat is currently undergoing profound changes. Various military strategies and technologies have continuously emerged， such as distributed killing， mosaic warfare and para-suppression engineering. Against this background， this paper focuses on analyzing the characteristics of multi-domain integration in the Russia-Ukraine war， summarizing two major challenges including performance boundary and physical boundary， proposing the development direction of collaborative detection and guidance based on full-domain holographic situational awareness， refining eight key technologies including but not limited to the generic collaborative detection and guidance system architecture， and exploring the ways of implementation. The evolution of detection and guidance technology is promoted to multi-domain joint， cross-domain collaboration and full-domain countermeasure， supporting higher-level information-based warfare in the future.
