小口径速射舰炮武器系统反导射击方法研究

小口径速射舰炮受弹鼓容量及舰炮发射系统限制,一般不能在舰炮武器系统有效射击范围内全航路持续射击,这就要求对射击方法进行研究。应用蒙特卡洛法,在MATLAB软件平台上计算了小口径速射舰炮武器系统对匀速直线运动导弹的命中概率与弹丸相遇点距离间的关系,提出了以全航路最大概率命中导弹有效部位为基础制定射击终止点,反推射击起始点的射击方法,提高了舰炮武器系统在全航路射弹数限定条件下的命中概率;以舰炮武器系统跟踪器最大跟踪角速度限制因素为例,分析了导弹运动速度、航路捷径与射击区域的对应关系,并应用本方法对导弹典型航路的射击方案进行了仿真。仿真结果表明该方法在一定条件下能有效提高舰炮武器系统对导弹的全航路命中概率。

Fuzzy recognition of missile borne multi-line array infrared detection based on size calculating

In order to improve the infrared detection and discrimination ability of the smart munition to the dy-namic armor target under the complex background, the multi-line array infrared detection system is established based on the combination of the single unit infrared detector. The surface dimension features of ground armored targets are identified by size calculating solution algorithm. The signal response value and the value of size calculating are identified by the method of fuzzy recognition to make the fuzzy classification judgment for armored target. According to the characteristics of the target signal, a custom threshold de-noising function is proposed to solve the problem of signal preprocessing. The multi-line array infrared detection can complete the scanning detection in a large area in a short time with the characteristics of smart munition in the steady-state scanning stage. The method solves the disadvan-tages of wide scanning interval and low detection probability of single unit infrared detection. By reducing the scanning interval, the number of random rendezvous in the infrared feature area of the upper surface is increased, the accuracy of the size calculating is guaranteed. The experiments results show that in the fuzzy recognition method, the size calculating is introduced as the feature operator, which can improve the recognition ability of the ground armor target with different shape size.     

Decision support model for effects estimation and proportionality assessment for targeting in cyber operations

Cyber operations are relatively a new phenomenon of the last two decades.During that period,they have increased in number,complexity,and agility,while their design and development have been processes well kept under secrecy.As a consequence,limited data(sets)regarding these incidents are available.Although various academic and practitioner public communities addressed some of the key points and dilemmas that surround cyber operations(such as attack,target identification and selection,and collateral damage),still methodologies and models are needed in order to plan,execute,and assess them in a responsibly and legally compliant way.Based on these facts,it is the aim of this article to propose a model that i))estimates and classifies the effects of cyber operations,and ii)assesses proportionality in order to support targeting decisions in cyber operations.In order to do that,a multi-layered fuzzy model was designed and implemented by analysing real and virtual realistic cyber operations combined with interviews and focus groups with technical-military experts.The proposed model was evaluated on two cyber operations use cases in a focus group with four technical-military experts.Both the design and the results of the evaluation are revealed in this article.
