In the face of the complex air-space-ground integrated battlefield environment in the future, this paper aims to analyze the important nodes in the battle-level "OODA loop" and some concepts of the related situational awareness information cognitive model have to clarify, and clarifies the specific pilot needs in the cockpit information channel and the OODA loop process scenario, provides guidance for pilots to obtain integrated information situational awareness in the air to quickly cut into the enemy's OODA loop, implement strikes and gain battlefield advantages. From the perspective of the iterative development of fighter jets, the evolution process of the cockpit is analyzed, and the impact and trends of current technological development on the information structure and overall layout of the future cockpit are discussed. Through corresponding literature review, the situational awareness information requirements of pilots in each combat loop of the OODA loop are put forward. In addition, through the integration model, the fighter combat information in different stages and scenarios is integrated to form an integrated system of combat in the cockpit, and through the conceptual design, the pilot's movement requirements and the information space layout in the fighter cockpit are balanced to achieve a preliminary verification and expression theoretical framework. In conclusion, by analyzing the OODA loop in combination with the situational awareness model, the research on the integrated design of the fighter intelligent cockpit information system is carried out. Placing emphasis on the pilot's action requirements in the combat process, the fighter intelligent cockpit design via the integrated framework integrates with multi-source, multi-layer and multi-amount information. Furthermore, an information-integrated fighter cockpit design centered on the pilot's combat task action in the OODA loop combat process is deisgned to serve the army, which boasts guiding significance for future fighter design.
