合作定位节点选择策略

合作定位是指接收机之间通过合作网络交换关键定位信息实现协同定位的新技术,接收机进行合作定位过程中可供使用的辅助节点包括可视卫星和已定位邻居接收机。接收机之间的合作增加定位过程中的可用辅助节点数量,进而增加位置估计的计算量和计算时间,在可用辅助节点较多时,定位实时性很难得到保证。提出改进次优节点选择算法,计算备选节点之间单位向量差作为节点价值,选择拥有最大价值的节点作为辅助节点。将新算法与4种典型的节点选择算法进行了对比,仿真实验证明该算法能够在较短时间内选择出接近最优算法得到的组合,综合性能优于现有节点选择算法。     

中远程空空导弹多机协同中制导交接方法

针对在同类型空中平台协同作战条件下,中远程空空导弹中制导权在移交过程中存在信息突变的问题,提出采用"虚拟目标"法对突变信息进行渐近处理,使虚拟目标逐步向真实目标运动,最终"导弹—虚拟目标"视线角与"导弹—真实目标"视线角重合,则中制导权移交结束;提出三种不同的中制导权交接律,在目标不机动/机动两种情形下,通过仿真分析不同模式下的交接律对空空导弹过载的影响。仿真结果证实适当平缓地进行制导权移交能将突变信息转化为接近于目标机动形成的、导弹自身能够处理的突变信息。避免了直接交接使导弹过载突变到非正常值的情况,使中制导交接能够平稳进行。     

Cooperative interception with fast multiple model adaptive estimation

For the case that two pursuers intercept an evasive target, the cooperative strategies and state estimation methods taken by pursuers can seriously affect the guidance accuracy for the target, which performs a bang For the case that two pursuers intercept an evasive target, the cooperative strategies and state estimation methods taken by pursuers can seriously affect the guidance accuracy for the target, which performs a bang-bang evasive maneuver with a random switching time. Combined Fast multiple model adaptive estimation (Fast MMAE) algorithm, the cooperative guidance law takes detection configuration affecting the accuracy of interception into consideration. Introduced the detection error model related to the line-of-sight (LOS) separation angle of two interceptors, an optimal cooperative guidance law solving the optimization problem is designed to modulate the LOS separation angle to reduce the estimation error and improve the interception performance. Due to the uncertainty of the target bang-bang maneuver switching time and the effective fitting of its multi-modal motion, Fast MMAE is introduced to identify its maneuver switching time and estimate the acceleration of the target to track and intercept the target accurately. The designed cooperative optimal guidance law with Fast MMAE has better estimation ability and interception performance than the traditional guidance law and estimation method via Monte Carlo simulation.     

潜艇自航式诱饵组合使用研究

潜艇自航式诱饵组合使用方法的优劣主要评判依据是使用的方法最终使得潜艇对抗鱼雷成功的概率,对抗时间和诱骗距离是影响对抗成功概率的两个重要因素,它们又主要围绕发射时机、初始航向以及潜艇机动等几个问题展开。该文通过分析各个诱饵的作战使命,在一定态势下,根据诱饵的性能、鱼雷报警距离及舷角等各方面因素,建立大小口径声诱饵协同作战的弹道模型,并由此得到了诱饵发射时机、初始航向等参数。

Initiating a cooperative denuclearization effort with North Korea

ABSTRACT

As the United States and North Korea pursue negotiations on a “denuclearization” agreement, the two countries should consider initiating cooperative measures as a way to build confidence and encourage finalization of a complete agreement. Based on lessons from the initial engagements carried out under the Cooperative Threat Reduction (CTR) program in states of the former Soviet Union (FSU), initial cooperation should focus on safety and security, training, and infrastructure elimination. By offering to implement these initiatives now while negotiations are underway, the United States could gain additional insights into North Korean intentions. These early initiatives could be proposed without compromising the US maximum-pressure campaign on North Korea by using the current authorities of the CTR program and carefully designing specific exemptions that may be required for any agreed measures. If North Korea is truly interested in pursuing disarmament efforts, the initial cooperative projects would enable them to begin reaping potential benefits while negotiations continue with sanctions still in place. These initial proposals could also be expanded to include additional international partners such as Russia, China, South Korea, and Japan. Such programs and initiatives would support and supplement longer-term strategies to address North Korean weapons-of-mass-destruction challenges.
