The network information system surrounding information acquisition, information interaction, and information utilization is the core element of the current information environment, and the measurement of information is one of the cores of the research on the network information system. This article quantitatively calculates different levels of information from the perspective of effectiveness evaluation, maps the information measurement issues in the physical domain, system domain, and system domain to the equipment performance, system effectiveness domain and system effectiveness, and quantitatively calculates the information from the perspective of application effects, get the multi-scale measurement framework of information measurement. Through this framework, multi-scale quantitative calculations can be carried out on the information application capabilities of different levels of network information systems, providing support for equipment construction, capability evaluation, and optimized applications.

The integrated and coordinated operation of warships and aircraft is the core issue of air-sea battle control. Ship antiaircraft and carrier-based aircraft are vigilant in different airspaces. In the face of uncertain threats, the defense effects of ships and aircraft are different, and in order to avoid the overlap between ship firepower and aircraft firepower, The assignment of goals becomes very important. Based on the zoning principle of warship and aircraft cooperative defense, this paper proposes a target attack time calculation method for combat situation. By calculating the estimated time of the attack and threat of the ship and the aircraft at the current position as the estimated interception time, factors such as the maneuver time of the aircraft, the flight time of the weapon, and the interception area need to be considered. Based on this method, the target grouping algorithm with minimum target intercept time is given. According to the algorithm, the warship-to-aircraft cooperative air defense is realized. The Monte Carlo simulation analysis is carried out on the two combat situations in the dynamic combat simulation platform. By comparing the simulation results, we find that the proposed algorithm can effectively reduce the damage rate of the warship.

With the deterioration of battlefield environment, joint combat will become an important mode of operation in the future. In this paper, the Department of Defense Architecture Framework (DoDAF) is studied, the architecture framework design ideas and specific architecture design steps of DoDAF are given, the architecture views involved are described. This paper presents a DoDAF-based modeling method for air-sea joint combat system architecture, which can better describe the operational tasks, information relations among constituent nodes and sub-systems of the complex integrated air-sea joint operation system. This method is often used in the early development stage of complex systems, and enhances consistency understanding between application personnel and system designers and developers.
Based on the operational requirements of the future of naval warfare and electronic warfare, according to the composition of the electronic systems of maritime battle groups, analysis of the overall capacity needs of the electronic information warfare. The way of electronic warfare UAV is proposed for in information confrontation. And we analysis early warning radar’s simulation model and electronic warfare process. Then we analysis the detection model of early warning radar in noise jamming, in densely false targets jamming, in repeater jamming and Integrated suppression of jamming. This paper build a simulation platform based on the demand for electronic countermeasures system. Simulation experiments, by comparing the assessment indicators, the results illustrate some typical problems of the penetration of electronic warfare UAV to aircraft carrier battle group, penetration aircraft carrier battle group when electronic warfare UAV load optimization and a variety of typical scenarios route planning recommendations.
In future battlefields, UAVs play an increasingly important role and need to perform a variety of tasks. The UAV avionics system is also becoming more and more complex. In order to achieve flexible deployment and utilization of UAV avionics resources for various tasks, the composition and workflow of the UAV avionics system are firstly studied. Then the servitization process is studied based on UAV avionics resources. At last, extraction methods from resource to service and service management mode are described, to provide support for the UAV to realize the intelligent and autonomous operation.
