基于CPSO算法的海空跨域无人航行器集群协同作业路径规划

针对海空跨域无人航行器集群在复杂水域环境下协同作业以追踪水下目标的任务,提出一种基于协同粒子群(CPSO)的协同作业路径规划算法.考虑不同无人航行器集群特性优势,合理分解并分配远距离追踪水下目标任务过程,并利用CPSO算法进行路径规划.在CPSO算法中,首先为无人机(UAVs)集群规划飞行路径,UAV飞行过程中探测水面...     

The People’s Liberation Army and China’s Smart Power Quandary in Southeast Asia

Abstract

China has a strong interest in pursuing a smart power strategy towards Southeast Asia and has worked laboriously to engage with regional countries economically, socially, and politically. But China has been only partially successful in achieving its goals in the region. This paper argues that China’s security policy towards Southeast Asia significantly contradicts many other objectives that Beijing wishes to accomplish. Given the deep-seated, narrowly-defined national interests of the Chinese military in the South China Sea disputes, it is likely that the People’s Liberation Army (PLA) will continue to pose the main obstacle to the effective implementation of a Chinese smart strategy in Southeast Asia.     

Understanding China’s goals and strategy in the South China Sea: bringing context to a revisionist systemic challenge – intentions and impact

ABSTRACT

The slow moving conflict in the South China Sea has been characterized by some as “not worth the candle.” China claims the entirety of the South China Sea pursuant to a nine-dash line, the legal impact of which has been limited by international courts. At the same time, China has changed the reality of control over the South China Sea by building a number of fortified islands in the Spratly Islands and elsewhere. The US has either refused to stand up to China's behavior (Obama) or responded unevenly (Trump). This paper examines the impact of China's behaviour on local parties, US interests, and the liberal international system.     

国际海洋法与维护国家海洋权益

海洋权益是指沿海国对属于自己的管辖海域享有国际海洋法所赋予的特定主权权利。《联合国海洋法公约》奠定了现代国际海洋法制度的基础，为各国维护正当的海洋权益提供了基本法律依据，但也有不完善甚至严重缺陷之处。认真研究其利弊，以切实维护国家海洋权益和公正合理的国际海洋法律秩序。

台风浪过程对空中飞行器生存能力的影响分析

为了分析台风浪对飞行器生存能力的影响,以CCMP风场驱动WW3海浪模式,对发生在2008年9月的台风"黑格比"所致的台风浪进行数值模拟,并就台风浪对导弹等飞行器击水概率的影响进行计算分析。研究发现:以CCMP风场作为WW3模式的驱动场,对发生在中国海的台风浪进行数值模拟是可行的,模拟的海浪数据接近海浪浮标观测数据;击水概率大值区主要分布于台风的大浪区,当飞行器的飞行高度为12m时,击水概率基本在15%以上,近台风中心更是高达26%～30%,台风大浪区的外围的击水概率则基本都在10%以下;当导弹飞行高度为15m时,击水概率基本只有12m时的一半;无论飞行高度为12m还是15m,击水概率的大值区均集中分布于该台风行进方向的右半圆。击水概率的高值中心并不位于台风中心,这应该是由于台风中心存在一低风速的台风眼造成的。该研究为提高掠海飞行器的生存能力提供参考。     

The Evolution and Significance of the 1972 Incidents at Sea Agreement

As a consequence of the rapid growth of Soviet maritime power during the 1960s, hazardous incidents at sea and in the air became a regular part of the Cold War. Eventually, both Washington and Moscow came to recognize the importance of an agreement limiting this perilous set of interactions, resulting in the Incidents at Sea Agreement that was signed in May 1972. The set of rules and procedures agreed upon helped to calm tensions in subsequent crises and provides ample lessons for placing reasonable limits on other tense maritime rivalries.     

The subversion of the Bulgarian defence system – the Russian way

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO.
