基于测高精度最优值的星载分布式InSAR编队构形设计方法

编队构形设计是分布式干涉SAR系统总体设计的关键问题,它必须紧密结合系统性能评价和编队运动规律进行。针对星载分布式干涉SAR的双站、斜视、空间基线等特点,以主星带辅星群分布式InSAR为例,建立干涉测高精度与基线矢量的关系;以直角坐标过渡,建立基线矢量与卫星间轨道根数差的关系,从而建立了测高精度与卫星轨道根数差的关系;以雷达工作的中间时刻达到测高精度最优值为设计准则,得到双星和多星编队设计方法;仿真分析表明根据上述设计方法得到的优化编队构形,其测高性能要优于干涉车轮和干涉钟摆编队。

Theoretical and numerical simulation study on jet formation and penetration of different liner structures driven by electromagnetic pressure

The use of a shaped liner driven by electromagnetic force is a new means of forming jets. To study the mechanism of jet formation driven by electromagnetic force, we considered the current skin effect and the characteristics of electromagnetic loading and established a coupling model of"Electric—Magnetic—Force"and the theoretical model of jet formation under electromagnetic force. The jet formation and penetration of conical and trumpet liners have been calculated. Then, a numerical simulation of liner collapse under electromagnetic force, jet generation, and the stretching motion were performed using an ANSYS multiphysics processor. The calculated jet velocity, jet shape, and depth of penetration were consistent with the experimental results, with a relative error of less than 10％. In addition, we calculated the jet formation of different curvature trumpet liners driven by the same loading condition and ob-tained the influence rule of the curvature of the liner on jet formation. Results show that the theoretical model and the ANSYS multiphysics numerical method can effectively calculate the jet formation of liners driven by electromagnetic force, and in a certain range, the greater the curvature of the liner is, the greater the jet velocity is.

From tirpitz plan to schlieffen plan: Some observations on German military planning

This article explains why the EU in recent years has gained an upper hand in Allied defence planning. The development is surprising in light of reforms undertaken by NATO in the mid-1990s and also the 1998-99 US ambition to reinforce NATO's defence planning process with the Defence Capabilities Initiative. The article argues that a number of European governments, notably including the British and French, has been motivated to seek change because NATO's defence planning process has proved difficult to adapt to new low-intensity threats and also because governments seek to control the political development of the EU itself. The article illustrates how these concerns are directly visible in the current EU design for military planning and offers an assessment of future NATO-EU relations.
