Battlefield situational awareness is the core condition that determines the success or failure of the battlefield, and it is also an important application direction of photodetectors. The rapid development of AI technology in recent years is about to cause major changes in future wars. The new AI battlefield will also put forward new urgent needs for situational awareness. This article summarizes the current main modes of collaborative detection of battlefield situation awareness and its research status, including radar / infrared composite detection, multi-source data fusion of radar / infrared detection, cooperative target recognition, target tracking, etc. On this basis, combined with the current development trend of the intelligence level of the main battlefield equipment, we get the development needs of future intelligent battlefield situational awareness for new types of collaborative detection, including requirements for its style, angle, speed, and detection targets of distributed collaborative detection. Based on this, the key development directions and core issues to be solved for intelligent battlefield situational awareness in the future are proposed.
This article summarizes the reports and researches on detection system of STSS published in domestic and foreign literature, summarizes the development process of STSS detection system from a single geostationary orbit to a combined large elliptical orbit, then to the development process of the high-track network and the low-track network cooperate with each other. It also summarizes the development process of infrared detectors from single-band to multi-band, from line scan with less detection pixels to line scan with more detection pixels and large-area staring array. The application scenarios, overall scheme, and overall parameters of the STSS detection system are sorted out, and the core technical indicators are analyzed for the overall parameters. From the perspective of the development process of the US early warning satellite system and the technical characteristics of the space-based infrared system, US early warning satellite technology is of great significance to research on US defense programs, equipment, and system capabilities.
