    To improve the accuracy of Low altitude unmanned aerial vehicle(UAV) target detection and tracking, an improved UAV detection algorithm based on YOLOv7 and DeepSort framework is proposed. The CBAM attention mechanism is introduced into the backbone network of YOLOv7 algorithm to improve feature extraction ability. To improve feature fusion ability at different scales, BiFPN weighted feature pyramid is used to replace PANet, and a small target detection layer is added to improve the detection accuracy of small target UAVs. A "low slow small" human-machine data set is constructed with four types of backgrounds: sky, trees, buildings, and dark conditions. The experimental test is carried out. The results show that the detection part mAP@0.5 of the improved algorithm is improved by 8.6%, and the detection accuracy of small-size and weak-feature targets is improved by about 21%. In the final tracking result, the MOTA index was increased by 24%, and the correct output target box accounted for about 70% of the true target box.

    In order to meet the development requirements of unmanned aerial vehicle (UAV) boosters, a detachable launch booster for fixed wing UAVs was designed, which is driven by high-pressure carbon dioxide gas. A mathematical model for gas launch was established based on the internal ballistic equation of the gas cannon. Through theoretical calculations and the use of dynamic simulation software ADAMS to simulate the designed 3D model, the variation laws of initial velocity, overload, displacement, etc. during the launch of unmanned aerial vehicles of different masses were obtained. The results show that the initial velocity, displacement, and overload variation curves obtained through simulation when the drone leaves the launch pad are highly consistent with the theoretical calculation results, verifying the correctness of the calculation and simulation. The research results indicate that the fixed wing unmanned aerial vehicle (UAV) booster launcher can successfully launch UAVs weighing 14 kg or less and achieve initial takeoff speed without exceeding maximum overload. The simulation results have an error of no more than 3% compared to theoretical calculations. The research results can further provide theoretical guidance for gas emission.

    Aiming at the problem of how to select high risk key defense area under the condition of limited urban defense force, to maximize the utility of limited force and minimize the urban risk, this paper proposes a method of selecting key defense area based on regional comprehensive risk assessment. Firstly, a reasonable risk assessment index system is constructed from the perspective of the intruder and the defender. Secondly, based on the idea of equivalent energy, the weight product normalization method is proposed to determine the combined weight of the target risk index, and then calculate the target risk value. Then, according to the centroid theory, the weighted centroid calculation model of target distribution is constructed, and the dispersion matrix is established to calculate the dispersion of regional target distribution. Finally, the regional comprehensive risk assessment function is constructed according to the area of risk radar map, and the comprehensive risk of each region is quantitatively assessed according to the target situation of districts I to VI of a city. The results show that compared with the target risk coupling method, the proposed method can realize the regional comprehensive risk assessment more accurately, and provide decision-making basis for the selection of key urban defense areas and the efficient deployment of limited forces.

    The complexity of war games poses challenges for single-technique-built agents, as it requires balancing between coarse-grained strategic adjustments and fine-grained action control, thus limiting agent performance. To address this, this paper proposes a multi-level agent architecture for military strategy games based on the "Intent-Task-Action" framework, aiming to integrate various technical strengths for intelligent agent modeling in these games. Through a top-down decomposition and propagation mechanism, this architecture progressively breaks down combat strategies into executable tasks and actions. Techniques such as Finite State Machines, Coalition Games, and Behavior Tree are employed to implement the different levels of the agent architecture. The application scope of the realized agent is preliminarily defined as the tactical level scenario of the land combat unit. Finally, through multi-round adversarial experiments with various benchmark AI on a war gaming platform, the feasibility and effectiveness of the proposed architecture are validated.

    This paper mainly studies the deployment scheme of the single base sonar and bistatic sonobuoys with the least number of sonars when blocking the potential area of the target submarine. Under ideal sea conditions, the minimum amount of sonar is required when the intersection line between the detection area and the target area is the diameter of the detection area. Therefore, a bistatic optimal array scheme is proposed in this paper. In the same equivalent radius, the difference between the number of sonars required by this scheme and the optimal array of single-base sonar is only -1 to 1. Finally, this paper verifies the effectiveness of the deployment scheme through experimental simulation, and calculates the number of sonar required for each scheme, which has guiding value for the anti-submarine area blockade.

    With the rapid development of artificial intelligence technology, intelligent weapon equipment is playing an increasingly prominent role in future urban warfare. This paper aims to propose a scientific method to determine the development strategy for intelligent weapon equipment for urban combat. Firstly, the characteristics of urban warfare and the development status of intelligent weapon equipment are analyzed. The fuzzy analytic hierarchy process (FAHP) is innovatively introduced into the SWOT analysis framework. This model utilizes FAHP to process the subjective SWOT analysis matrix, quantitatively calculating the weights of influencing factors, and improves the deficiency of traditional SWOT analysis relying too much on expert experience. Meanwhile, an improved calculation method for the centroid coordinates of the strategic quadrilateral is proposed, presenting a more reasonable coordinate calculation formula that can more accurately determine the centroid position. Finally, taking the intelligent weapon equipment for urban warfare as an example, the opportunity-seeking and proactive strategy is determined through calculation, and suggestions for the corresponding development strategies are put forward.

    Special information system is a complex information system with specific architecture, clear functional positioning, and diverse components and relationships among elements, and the key point refers to the node or component element that plays a key role in the system, and the damage of "acupuncture point" will have a huge impact on the function and utility of the whole system. It is of great scientific value and practical application significance to study how to excavate the key points of the system. In this paper, the complex network theory is used to analyze the network characteristics of special information system. On this basis, from the two dimensions of "static" and "dynamic", five indexes are proposed respectively, namely, transcendence, clustering coefficient, eigenvector centrality, network elasticity and network destruction resistance, which are used to evaluate the importance of each node. Next, YAANP decision software is used to determine the weight of each index, and then a key "acupoint" mining method for special information system is proposed. Finally, taking the special information system under the background of urban unmanned attack operation as an example, the scientific and reasonable of the proposed method is verified.

    During the operation of rocket mine laying system, due to the influence of wind speed and direction, the landing position of the mine is prone to deviate from the predetermined position after opening the cabin, which leads to the decline of mine laying operation efficiency. In this paper, a model for evaluating the operational efficiency of rocket mine laying bomb is established, the relationship between wind speed and wind direction and the landing position of rocket mine laying bomb is simulated and analyzed. The operational efficiency of rocket mine laying bomb is verified. The simulation results show that the rocket mine laying bomb is affected by crosswind level Ⅳ, and the landing position deviates greatly from the predetermined position. When the longitudinal wind speed reaches level VI, the land position of the rocket mine bomb deviates greatly from the predetermined position. The research results demonstrate the quantitative relationship between the operational efficiency of rocket mine laying bombs and wind speed and direction, which provides methodological support for the rational use of rocket mine laying system in actual combat environment.

    The size of the radar network coverage area is one of the important indicators to measure the performance of the air defense system, and it is of great significance to optimize the layout design of radar network and to maximize the comprehensive uniform chamber benefit of radar network. Since the probability of detecting a target by the radar network is the result of the joint action of various radars, the graph of its coverage area is very complex and difficult to obtain an analytical solution by conventional methods. By analyzing the relationship between the joint probability of multiple radars detecting a target and the radar parameters and target distance, the constraints are determined, and the basic idea of Monte Carlo method is used to transform the area calculation problem into a problem of calculating the number of points satisfying the constraints in a plane. The process of the specific algorithm is given. Compared with similar algorithms, the structure of this algorithm is clear and simple, and it is easy to extend. Through simulation experiments, the feasibility of the algorithm is verified.

    In order to design satellite with low cost and high effectiveness, an optimization method of life cycle cost-effectiveness for satellites is proposed in this paper. Since most satellites are unrepairable and their performances experience degradation in orbit, a life cycle effectiveness model based on ADC model is constructed. Then, a multidimensional parameter cost model is proposed to estimate the satellite cost. Finally, an optimization model and the solution method are developed by synthesizing the life cycle effectiveness model and the multidimensional parameter cost model based on CAIV. A remote sensing satellite is adopted to demonstrate the proposed method, the result suggests that this method could optimize the performance, reliability and weight indicators of satellite system, which might be applied for project design demonstration, task management, and life cycle cost control of satellites.
