Abstract: To address the operational requirements for early warning and detection situation products from users at different echelons and in various domains, a multi-scale early warning and detection situation product model is proposed. This paper elaborates on the model from the aspects of situation elements, composition rules, and the generation process. Furthermore, it introduces the key technologies involved in its practical application and presents a typical use case. The design and application of this model provide support for commanders and operators at all levels to rapidly grasp the battlefield situation, and are of great significance for enhancing the decision support capabilities of early warning and detection information systems.
