As the characteristics of warfare becoming even more multi-domain and full-dimension, a unified model framework is needed to ensure effective communication between teams and the consistency and interoperability among models. This paper proposes an OPM based on military operation model framework. Focusing on the process of military operation, the framework formalizes the elements of military operation, such as entities, environment, information and process, from a higher level of abstraction, providing a general template for the modeling of specific operating concepts. The framework includes three parts: top level conceptual model framework, operational entity model framework and operational process model framework. In addition, based on the framework, this paper models the mosaic warfare concept, and initially proves that the framework is suitable for the modeling of frontier operating concepts.

With the application of a large number of battlefield observation sensors, the battlefield target data input to the command and control system is increasing rapidly. The large scale, high dimension and complex structure of the target information data bring new challenges to the target clustering technology. However, the traditional clustering method cannot effectively cluster the high-dimensional battlefield target data. Aiming at the difficulties of current target clustering technology, this paper proposes an intelligent target clustering technology based on deep learning, constructs a target clustering model based on Deep Stack Auto-encoder Network, respectively embeds K-means and GMM into the target clustering model, and proposes two intelligent target clustering algorithms based on deep learning, namely DAE-k and DAE-G. By designing the verification experiment of intelligent target clustering technology, establishing the evaluation index of target clustering effect, the effectiveness and applicability of the two target clustering algorithms are verified, and the advantages and disadvantages of the two target clustering algorithms in processing different data types are obtained. The research of intelligent target clustering technology based on deep learning can make the command and control system process large-scale high-dimensional data more efficient and intelligent, and also provide technical support for the intelligent construction of command and control system.
The operating distance of infrared detection system is determined by the detector’s characteristics, target and background radiation, target pixel dispersion size and other factors. The traditional infrared operating distance equation does not consider the influence of point target under the effect of pixel dispersion, so the calculated detection distance is often more remote than the actual target, which seriously affects the commander’s decision-making. In this paper, the main factors influencing the formation of dispersion of point target on the detector target surface are analyzed, and the image pixel number of point target dispersion are calculated quantitatively, an improved operating distance equation considering the pixel dispersion size of the point target is derived. In the simulation example, it is analyzed that the operating distance of two kinds of infrared detectors, the corresponding relationship between the pixel number formed on the target surface and the detection distance is analyzed with or without considering the pixel dispersion. The validity of the model is verified by comparing with the measured data of target detection.

Finally, the Turkey weight function and the Gaussian weight function are combined into an adaptive segmented weight function for weight distribution. Experimental results show that the improved FNLM can effectively suppress coherent speckle noise while ensuring low time complexity.
