杂波

A theory of constrained matched filters is presented in this paper, by which the maximum output S/N ratio could be obtained under constrained conditions of nullifying clutter.

本文提出了一种条件匹配滤波器理论。条件匹配滤波器是在满足零化杂波约束条件下使输出信噪比达到最大的滤波器。

To describe the exterior environment where airplanes fly at low altitude, complex landform for minimum altitude flying was formed by planning multiple mountain ranges and many kinds of physiognomies.

由于地形遮蔽和地面杂波的干扰使得飞机在做超低空突防时不易被地面雷达发现，因此，低空和超低空突防逐渐成为现代战争中对敌方地面目标实施精确打击的主要作战方式。

Perhaps you've repainted, reduced clutter, and updated your kitchen, but you still feel something is missing.

或许你已经粉刷一，减少杂波，并更新您的厨房，但你还是会觉得事情是下落不明。

I'm not sure I like it, though, it squashes the results up and just adds extra clutter.

我不知道我喜欢它，不过， squashes结果和刚才增加了额外的杂波。

Compared to nearest neighbor , it shows better effects of the correct association rate and association time.

它以一个目标为中心的近似聚为构造关联事件的起点，并在计算中将DC 和AC 结合得到的一种全邻的点迹2航迹关联算法，在杂波下目标密集、航迹复杂的数据融合系统中进行实验，对关联正确率、关联时耗等与最近邻法进行了比较，效果较好。

The signal processing of narrow-beam radars are in the given direction to which the beam is pointing, so the received interferences and clutters only come from that direction and thus the signal-to-noise ratio is relatively high, and target detection is only need to be performed on the range-Doppler spectra, which has a relatively low demand.

而宽波束雷达则会接收到所有方位上的干扰和杂波，信噪比较低，除了需要在距离-多普勒谱上检测出目标外，还需要分别形成目标的阵列快拍以获取其空间谱估计。

You enter a webpage, and suddenly your window is filled with a myriad of annoying new little windows, multiplying like amoebas and cluttering your entire screen.

你进入网页，你突然窗口充满思绪恼人新小窗，2160杂波变形虫，你想整个屏幕。

Simulation results of tracking antiship missle in clutter were presented and analyzed to show the performance of the new method.

以杂波背景下反舰导弹类目标跟踪为例进行蒙特卡洛仿真，表明了这种方法有足够高的精度和良好的性能。

If you're one of those people who's got remote controls scattered across every inch of your coffee table, we've got the perfect high-tech gadget to get rid of that clutter of clickers once and for all: an elastic band.

如果您是其中之一，这些人的了远程控制设备遍布每一寸你的咖啡桌上，我们已经准备好了完美的高科技玩意儿，以摆脱这种杂波的clickers一旦和全部：弹性带。

I do not want much clutter so I chose simple hues of black, blue, grey, and red.

我不想多杂波，所以我选择了简单的色调，黑，蓝，灰，红。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
