雷锡恩公司的价值工程计划

价值工程是在事实形成之前、之后,或在形成的过程中,用集体工作分析成本和工程的方法来辨别出不必要的成本费用.用这一系统的有效性要依靠对用户的训练和技能的了解,以及了解在价值工程运用环境中的所有有关业务人员.它把工程、制造和采购注意力集中到一个目标上去——以较低成本达到所需性能.以此为中心,它用下列方法提供逐步改进所有起作用的部门的成本有效性:防止不必要的成本进入产品中;将存在的成本问题转变成额外的利润.     

PAMIR—一种宽带相控阵SAR／MTI系统

在未来的各种监视侦察任务中，机载及星载成像雷达系统必须满足越来越严格的要求。下一代最高水平的合成孔径雷达(SAR)系统将具有高灵敏度地面动目标指示能力和多种复杂工作模式，其中包括高分辨率和远距离成像能力。只有通过运用可重构相控阵天线连同综合宽带系统设计以及多通道能力才能完成各种任务。在FGAN已经设想出一种新的X波段实验雷达，该雷达最终将被改进成拥有由16个自动可重构子孔径组成的电控相控阵，5个独立的接收通道和大约1．8GHz的总信号带宽。这种传感器叫做PAMIR(多功能相控阵成像雷达)。着重用实例说明远距离超高分辨率SAR成像。借助于地面动目标的逆SAR(ISAR)成像也能实现高分辨率。而且，通过空时自适应信号处理和超高3一D分辨率单向干涉SAR(IfSAR)，接收通道的数目将提供地面动目标指示(GMTI)。在一个接收通道和机械控制天线阵列的情况下，PAMIR在其现行发展阶段中是切实可行的。文章介绍了PAMIR的系统设计和预期能力，并提供了高分辨率SAR及ISAR成像的地面及机载实验结果。     

A Canadian high-energy neutron spectrometry system for measurements in space

Bubble Technology Industries Inc. (BTI), with the support of the Canadian Space Agency, has finished the construction of the Canadian High-Energy Neutron Spectrometry System (CHENSS). This spectrometer is intended to measure the high energy neutron spectrum (approximately 1-100 MeV) encountered in spacecraft in low earth orbit. CHENSS is designed to fly aboard a US space shuttle and its scientific results should facilitate the prediction of neutron dose to astronauts in space from readings of different types of radiation dosimeters that are being used in various missions.

Prediction of Magnetospheric Disturbances Caused by a Quasi-Stationary Solar Wind

When predicting parameters of quasi-stationary Solar Wind (SW) streams at 1 AU, it is customary to use, as the indicator of solar sources, the Bases of Open Magnetic Tubes (BOMT) on the solar surface obtained via a calculation relying on a new Bd-technique of harmonic expansion of the magnetic field from daily full-disk magnetograms developed by Rudenko[4]. By considering an example of 17 events, it is shown that the correspondence between fast SW streams at the Earth's orbit and the BOMT, calculated with ≤ 24 h time resolution, makes up about 94%, while the correspondence of SW stereams with the CH in the light of the 10830 A line is about 29%. With this technique, the predictability of maxima of the Kp index of magnetospheric disturbance caused by a fast quasi-stationary SW, is over 90%, and the prediction accuracy of the maximun velocity vm of the stream is ±15%.
