Active protection simulation is a part of the field of system-of-systems confrontation simulation, and is the content of extensive research in the field of system-of-systems confrontation simulation at home and abroad. The main objective of the research is to accurately describe the active protection process and support the rapid development of computer simulation. This paper proposes an active protection simulation method, and implements an active protection software based on this method, which consists of armor protection simulation component, incoming ammunition detection and warning simulation component, soft killing active protection simulation component, hard killing active protection simulation component, etc. It can simulate the active protection process of armored target against typical ammunition. It not only considers the relevant elements of the protection process, but also facilitates the software implementation. It effectively supports the simulation of system-of-systems confrontation.
In view of the vulnerability analysis requirements of system targets, this paper puts forward the concept of system target vulnerability, defines system target vulnerability, analyzes the difference between system targets and single targets, and puts forward the analysis process of system target vulnerability, including preliminary determination of system target range, determination of vulnerability purpose and level, determination of key entities, construction of system damage tree, determination of damage weight and damage criteria, based on the analysis of single target vulnerability research results and other steps, this method can guide relevant work.
In order to meet the demand of accurate attitude measurement of high-speed targets, this paper proposes a high-speed target attitude recognition method, which includes ammunition attitude information measurement, small target rapid extraction from image sequences, ammunition axis image processing, target gray level recognition, etc. On the basis of multi camera shooting of targets, this method effectively identifies the terminal trajectory characteristics of ammunition through image fusion and image processing technology, Based on this algorithm, relevant algorithm models and software can be developed to guide practical application.
This paper presents a design method of basic mathematical simulation model of damage effect.

This paper presents a simulation algorithm for target to ground fire distribution. Taking battalion as an example, the algorithm for battalion level target to ground fire distribution includes the calculation model of optimal strike relationship, the cost function of missile control fire distribution and the solution method of linear programming. Based on this algorithm, the software is implemented and applied to related projects. Combined with the actual project, good results have been achieved.
This paper proposes an infrared modeling method, including infrared modeling process, target zero line of sight radiation modeling, atmospheric transmission effect modeling, infrared sensor effect modeling and so on. The infrared modeling method realizes the modeling of related entities, especially sensors, and the mapping of infrared materials. A complex, realistic and multi-element simulation environment is constructed to simulate and test the equipment system more effectively.
This paper presents a simulation method and software for the interaction between environment and equipment mobility, including the simulation model of the interaction between natural geographical environment and equipment mobility performance, the simulation model of the interaction between man-made battlefield environment and equipment mobility performance. The simulation environment elements can simulate equipment trafficability, collision detection and passage, which can effectively support equipment simulation.
