An access point's wireless card generates a very weak signal, so to minimize signal loss I wanted the antenna cable to be as short as possible.

访问点的无线卡会生成一个非常微弱的信号，因此，为了将信号丢失的情况降至最低，我希望能够将天线做得尽可能的短。

However, the scattered light is extremely weak and therefore yields a very low signal.

然而，这种散射光极其微弱，因此只产生一个非常弱的信号。

The experimental results show that the detector is very effective on extracting weak video signal from strong mixture noise.

实验结果表明，这种检测器对于从强混合噪声中提取弱视频信号是非常有效的。
