机载雷达目标搜索和跟踪中的坐标系问题

雷达对目标进行搜索和跟踪时,由于雷达的体制、安装方式(运载体还是地面固定位置)、工作方式等的不同,涉及到许多坐标系。结合实际工程问题,对雷达搜索与跟踪中坐标系问题进行了深入探讨。包括坐标系的定义、作用、坐标系转换问题,坐标转换中的误差定量分析,所得出的结论对于雷达对目标进行搜索与跟踪,尤其是对安装于运载体上的雷达坐标系问题有很大的参考价值,并给出了某型直升机载雷达挂飞时的实测姿态数据。     

The myth of Afghan electoral democracy: the irregularities of the 2014 presidential election

ABSTRACT

This article systematically assesses the 2014 Afghanistan Presidential Election, the first transfer of power from President Hamid Karzai to an elected successor, using provincial voting data as well as explicit data from polling centers. The analysis finds unusual voting results in the April election, where no candidate received 50%+1 votes required by the Afghan constitution, versus the voting results realized for the June ‘runoff election.’ As in other Afghan voting analyses, this article finds voting based on ethno-linguistic preferences, and interestingly found Dr. Ashraf Ghani receiving almost all the swing votes in the runoff election even though the other leading candidate from the April election all endorsed Dr. Abdullah Abdullah. More importantly, however, the research presented here clearly finds extremely strange voting patterns. For example, the polling data center analysis finds 606 polling places where Ghani received all 600 votes and Abdullah received none and another 900 polling centers that gave virtually all its votes to Ghani. These results in combination with other analyses raise the very real possibility that the election results were illegitimate. The article concludes with a discussion of the implications of the research to future Afghan elections and their processes as well as to the long-standing conflict in the country.     

HARNESSING GLOBAL TRADE DATA FOR BIOLOGICAL ARMS CONTROL

Unlike treaties dealing with nuclear and chemical weapons, the Biological Weapons Convention still lacks formal verification measures, 31 years after entering into force. Here we propose a global export-import monitoring system of biological dual-use items as an additional measure for a web of biological arms controls that could complement traditional export controls. We suggest that such a measure may help to guide consultation or verification processes in the biological area.
