Three-Dimensional Discrete Observability Analysis for Air-to-Air Missile Target Tracking

The interception information of infrared（ IR）-guided air-to-air missiles（ AAM） is mainly estimated only using the basic bearing measurements. In order to intercept highly maneuverable targets,it is essential to study the system observability to improve the target tracking system performance.The uniqueness of this paper is that the observability analysis is derived based on a discrete three-dimensional （3D） system model. During the maneuvering scenario,the system is approximated by a segment-by-segment system. The relationship between missile-target motion and observability is given by direct and dual approaches. Meanwhile sufficient observability conditions are derived. Moreover,a numerical simulation is conducted and an alternate method is provided to reinforce the proposed observability analysis results.

Dynamic attack zone of air-to-air missile after being launched in random wind field

A new concept is presented for air-to-air missile which is dynamic attack zone after being launched in random wind field. This new concept can be used to obtain the 4-dimensional （4-D） information regarding the dynamic envelope of an air-to-air missile at any flight time airned at different flight targets considering influences of random wind, in the situation of flight fighters coop- crated with missiles fighting against each other. Based on an air-to-air missile model, some typical cases of dynamic attack zone after being launched in random wind field were numerically simulated. Compared with the simulation results of traditional dynamic envelope, the properties of dynamic attack zone after being launched are as follows. The 4-D dynamic attack zone after being launched is inside traditional maximum dynamic envelope, but its forane boundary is usually not inside traditional no-escape dynamic envelope; Traditional dynamic attack zone can just be reliably used at launch time, while dynamic envelope after being launched can be reliably and accurately used during any flight antagonism time. Traditional envelope is a special case of dynamic envelope after being launched when the dynamic envelope is calculated at the launch time： the dynamic envelope after being launched can be inflt, enced by the random wind field.

俄核动力巡航导弹剂量空间分布研究

俄核动力巡航导弹消息发布后,其飞行期间放射性影响是关注的重点问题之一。俄方技术资料公布较少,依据美国核动力导弹TORYⅡ-C地面试验的测试数据,核动力发动机近距离处辐射剂量率很高;但是短时间的运行后,对试验场外环境的影响可以忽略。对于俄核动力巡航导弹飞行过程中反应堆中子、光子直接辐射的影响与空气活化的影响,可以设置合理的评估指标,依据GB 18871—2002建立分析方法进行计算评估。结果表明,空气活化产物的有效剂量贡献相对于中子、光子直接辐射的有效剂量贡献几乎可以忽略。对于推算的以5 MW反应堆为动力的俄巡航导弹,如果不考虑燃料裂变产物的泄漏,导弹从空中飞行一次形成的有效剂量,在与其飞行轨迹法向距离大于80 m的范围,将低于GB 18871—2002中50 mSv的工作人员年剂量限值。

美俄《中导条约》履约争议及其未来走向

2014年7月,美国国务院在其发布的年度军控条约履约报告中公开指责俄罗斯违反美国与苏联于1987年签署的《中导条约》,并引发两国新一轮外交对抗,将美俄长期存在的围绕《中导条约》争议推向新的高度。美俄围绕《中导条约》之所以争议频频,既有历史根源,也有安全考虑,更有现实政治因素。《中导条约》的未来将取决于美俄双边政治动态演变及其对两国安全环境的影响。从短期看,美俄仍将重点解决《中导条约》的履约问题;从长期看,美俄很有可能再度推动条约多边化。
