Under the terms of the initial ＄42 million contract with the Command's Robotics and Unmanned Systems Program Management Office, Northrop Grumman will deliver 10 STARLite Synthetic Aperture Radar/Ground Moving Target Indication radars to the Army.

根据与该司令部机器人技术与无人系统项目管理办公室的4200万美元初始合同，诺斯罗普·格鲁曼公司将向美国陆军交付10部STARLite合成孔径雷达/陆地移动目标指示雷达。

Simulation results of initial hole included the relationship of punch load and punch stroke, the hole profile, the distribution of stress and strain, the forming limit diagram, and the variation of the workpiece thickness. The simulation results showed good agreement with the experiments in the bore-expanding process.

由初始孔径4mm之料片於扩孔成形之数值模拟与实验结果比较得知，冲头负荷与冲程关系、内孔轮廓大小、应力与应变分布、成形极限图与工件厚度分布等，皆显示实验与数值模拟间的一致性。

In SAR azimuth signal processing, it is very common to subsample the raw data with a filter, which may reduce the Signal Noise Ratio of the raw image.

摘要机载合成孔径雷达的方位向降采样经常会降低原始图像的信噪比。

The proposed scheme is achieved by extracting the support of an indicator function on a sampling domain containing the penetrable object as a visualization of the unknown object where the indicator function has noticeably different values inside and outside the penetrable object.

这个算法的一个特别吸引人的性质是不需要关于障碍物的任何几何和物理的先验信息，并且只需要散射场在某个有限孔径中若干个入射和测量方向上的远场信息，即可得到可穿透目标的一个很理想的可视化。

The microwave absorbing performance of frequency selective surface with resistance patch was analyzed in this paper.

1引言频率选择表面是二维周期性导体贴片或孔径单元阵列，具有带阻或带通的滤波特性，其频率滤波特性来自它的周期性结构与电磁波的相互作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
