SLOWING DOWN TO KEEP THE LEAD IN MILITARY TECHNOLOGY

We develop a model of military technology competition among states. States can choose to introduce new military technology, mimic rivals’ level of technology, or withdraw from the contest. States can choose to implement any level of technology within their current feasible technologies. We find that states with significant technological leads should sometimes withhold new technologies, only strategically releasing them to trump rivals’ efforts. We develop the model by refining Admiral Jackie Fisher’s roughly articulated concept of ‘plunging’. We then use this refined argument to reanalyze the case of naval rivalries among European powers between the Crimean War and the First World War. Finally, we conclude by discussing the model’s implications for current US military force structure planning.     

Country Survey XIII: Japan's security posture and defense industry prospects

Defense budgets in Japan have been complicated compromises from numerous inputs ‐ including threat perceptions, domestic industrial/technological base development, support for the bilateral security treaty with the United States and internal bureaucratic politics ‐ but with the fall of the former Soviet Union, the clearest justification for higher spending disappeared. Double‐digit defense spending increases that were common in the 1980s have been replaced by annual increases lower than present inflation rates, resulting in negative real growth in the country's defense budget. Domestic economic problems and consistent government pressures for smaller budgets have further slowed annual growth in total spending and have contributed to lower procurement budgets. As a result, the domestic Japanese defense industry is facing far more constrained conditions from the growth years of a decade before.

Government policymakers are examining Japan's regional security environment as well as its alliance with the United States to determine the appropriate course for the country to take in the coming years. The formal security treaty with the United States is likely to remain a major element of government positions, but other aspects of the country's overall security posture are open to debate. Perceptions of a reduced threat environment are fueling additional pressures for defense budget cuts.

The domestic defense industry seeks means to assure its survival in domestic defense markets in this constrained environment. Expansion into overseas markets to offset declining domestic markets is an option that currently is constrained by policy restrictions on arms exports. Industry is advocating re‐examination of those policies and unlike earlier years, government appears willing to respond positively but cautiously to this lobbying.     

Portfolio analysis for defense: taking account of networking

To manage their assets at an enterprise level, defense organizations have turned to portfolio theory for the planning, analysis and management of their military forces and materiel. Despite being well established in the commercial sector, the application of portfolio approaches in defense is problematic. The vexatious question for defense of how to define and measure benefits arising is complicated by the increased utility and effectiveness achieved through networking of military forces and the equipment they use. The authors discuss the challenges for defense in using a portfolio approach and propose a conceptual model for dealing with the effects arising from networking with information and communications technologies.     

公安边防工作中情报主导警务与社区警务结合之途径浅探

情报主导警务已成为继社区警务之后的新工作模式。但在实际的公安边防工作中,情报主导警务的推广并不能完全取代社区警务。为此,在比较美国情报主导警务与社区警务模式的基础上,分析了情报主导警务与社区警务结合的必要性及紧迫性,重点探讨在公安边防工作中情报主导警务与社区警务优势相结合的途径。

一种抗云雾散射干扰的激光引信信号检测方法

激光引信在云雾环境中工作时,云雾的后向散射信号对其正常的目标信号检测产生干扰,严重时有可能引起虚警。研究了云雾产生的后向散射信号与目标回波信号的不同特点,并由此提出了双门限检测方法,即同时对信号幅度与信号幅度的增速进行检测,从而有效识别云雾干扰信号以避免产生虚警。通过分析实际的试验数据,对回波信号的特点进行了验证,实际应用双门限检测方法,验证了其可行性。     

空中目标运动参数实时测量系统

为了实现对飞机等远距离空中目标运动参数的实时测量,设计了目标自动跟踪测量系统,并对该系统的硬、软件组成及关键技术进行了研究。组建验证样机,进行软件框架设计及功能模块分析,通过实测实验详细测试了系统的工作性能。静态验证实验结果表明:测距结果稳定在1mm以内,方位测量结果稳定在5″以内。动态验证实验结果表明:对运动目标的实时测距误差为2mm,实时测距频率为5Hz;方位测量误差为0.05°,姿态测量误差维持在0.2°以内,方位和姿态实时测量频率均为20Hz。因此,系统满足空中目标运动参数稳定可靠、高精度的自动实时测量需求。
