• 结果美国F-117A一类的隐形战机雷达反射信号出仅仅如一只小鸟并非架飞机

    The overall result is that a stealth aircraft like an American F-117A reflects the radar signature of a small bird rather than an airplane.

  • 雷达信号接触飞机任何部位,都会有部分反射回来

    No matter where the radar signal hits the plane, some of the signal gets reflected back.

  • 隐形飞机依赖外形逃避雷达这种外形能避免雷达机体资源反射信号、且含有能吸收雷达能量物质

    Stealth aircraft rely on shapes that prevent radar waves from bouncing back to their sources and on materials that absorb radar energy (stealth-plane time line).

  • 结果表明:应用该文所介绍处理方法不但有效压制探信号中的随机干扰而且能精确确定反射起跳点

    The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave.

  • UWB雷达可以穿透墙壁天花板地板,而其他类型无线电信号被这些东西挡住反射

    UWB radar can see right through walls, ceilings and floors that would block or reflect other types of radio signals.

  • 新的雷达更多的是共鸣信号而不单单是反射

    New RADAR technology USES frequency resonance rather than the reflection of the signal itself.

  • 信号空间包含目标边界特征参数向量中非直流部分投影到信号子空间,得到场景内目标细节信息,然后据此估计场景各点雷达反射截面(RCS)。

    The variable part of the parameter vector is projected onto the signal subspace to identify intrinsic structural features of the scene and estimate the RCS.

  • 文章分析了调制脉冲激光雷达探测信号水下传输模型研究了海水后向散射信号以及目标反射信号特性

    The article analyses the seawater transport model of the modulated-pulse LIDAR signal, and the frequency characteristic of the seawater backscattering signal and target reflecting signal are studied.
