美国海军21世纪战略概念分析（连载一）

本文介绍名为“21世纪海上力量”的美国海军21世纪战略概念,阐述其各要素的内涵、现状和未来,并对“21世纪海上力量”做一些粗浅的分析。     

探雷声纳背景图像仿真的快速实现

为了真实地模拟海底背景,提出了一种适用于探雷声纳模拟训练的背景图像仿真快速实现方法,该方法将声波照射三维起伏海底掠射角的随机性体现在海底底质的比例系数中,可以逼真地仿真出各种起伏海底的背景图像,仿真计算时间小于探雷声纳最小重复周期,满足了探雷声纳模拟训练的需要。     

Regina Maris and the Command of the Sea: The Sixteenth Century Origins of Modern Maritime Strategy

The concept of the command of the sea has its roots in medieval notions of the sovereignty of coastal waters, as claimed by several monarchs and polities of Europe. In the sixteenth century, a surge of intellectual creativity, especially in Elizabethan England, fused this notion with the Thucydidean term ‘thalassocracy’ – the rule of the sea. In the light of the explorations of the oceans, this led to a new conceptualisation of naval warfare, developed in theory and then put into practice. This falsifies the mistaken but widespread assumption that there was no significant writing on naval strategy before the nineteenth century.     

The Dao of foreign policy: Understanding China’s dual strategy in the South China Sea

In the South China Sea, China neither implements power-maximizing policy nor engages a peaceful approach. Instead, China implements both coercion and cooperation in pursuing its strategic interest in the disputed area. How can we explain China’s paradoxical behavior? This article claims that the best way to explain China’s policy in the South China Sea is to understand the character of dualism in China’s strategic culture. Following constructivist theory that stresses culture, this article argues that Chinese duality approach in the South China Sea is rooted in the philosophy of Daoism. The symbol of Yin-Yang depicts Chinese assertive as well as cooperative behavior in dealing with the South China Sea dispute. Although from a normative perspective Daoism recognizes pacifism and non-violent behavior, the most important feature of Daoism is the assumption that reality consists of two opposing elements that are mutually embedded.     

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.     

舰载无人机雷达、通信侦察载荷在海战场打击效果评估中的运用

舰载无人机运用各种侦察载荷对目标进行搜索、定位,并在目标遭受打击后获取各类毁伤信息,是海战场目标打击效果评估过程中至关重要的环节。文章分别从对目标探测定位、毁伤信息获取、突防和返航等阶段,分析了舰载无人机雷达、通信侦察载荷的运用过程,讨论了雷达、通信侦察载荷在目标遭遇打击后毁伤信息获取中的具体应用,提出了雷达、通信侦察载荷在整个打击效果评估过程中使用应注意的问题。     

Russia’s strategy for influence through public diplomacy and active measures: the Swedish case

Russia, as many contemporary states, takes public diplomacy seriously. Since the inception of its English language TV network Russia Today in 2005 (now ‘RT’), the Russian government has broadened its operations to include Sputnik news websites in several languages and social media activities. Moscow, however, has also been accused of engaging in covert influence activities – behaviour historically referred to as ‘active measures’ in the Soviet KGB lexicon on political warfare. In this paper, we provide empirical evidence on how Russia since 2014 has moved towards a preference for active measures towards Sweden, a small country in a geopolitically important European region. We analyse the blurring of boundaries between public diplomacy and active measures; document phenomena such as forgeries, disinformation, military threats and agents of influence and define Russian foreign policy strategy. In summary, we conclude that the overarching goal of Russian policy towards Sweden and the wider Baltic Sea is to preserve the geostrategic status quo, which is identified with a security order minimising NATO presence in the region.     

近期美国海军南海地区活动态势分析

随着南海地区力量结构和美对华战略的转变,南海地区成为中美战略博弈的焦点。为围堵遏制中国的崛起,美国针对中国在南海实施了一系列海上挑衅行为。美国海军作为美国军事干预的主要力量,从兵力部署、演习演训、“航行自由”行动等着手,积极拉拢域内外盟友,展开并强化了在南海地区的军事活动。这些军事活动表现出极强的针对性和实战性,致使中美海上摩擦和竞争加剧。未来,美国为维护主导的全球秩序,将进一步提升美国海军在南海地区的威慑力。美国海军会借助并增加域内盟友的军事力量,继续维持高强度的装备平台活动及“航行自由”行动,推动海上力量合作。     

From show of force to naval presence,and back again: the U.S. Navy in the Baltic, 1982–2017

This article discusses roles and missions of the United States Navy with a particular focus on the Baltic Sea. That particular sea has gained renewed political and military attention following Russia's resurgent and increasingly hybrid-offensive foreign policy. Baltic nations, uncertain of what the future holds, ought to look at sea power and maritime missions in the Baltic, as well as US naval presence in Europe, to draw lessons for future posture.
