Background and interference

Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems.

当然，就像今天的其他环境问题一样，这是在全球变暖和人类干涉自然生态系统的背景下发生的。

Advanced circuitry reduces false alarms from background interference and a sensitive tuner allows you to automatically scan variable distances and channels.

先进的电路，减少干扰的背景调谐器和一个灵敏的假警报，您可以自动扫描变量的距离和渠道。

The optimum detector for passive detection is energy detector. Yet energy detector usually deteriorates due to fluctuation of background interference and a decrease in SNR.

被动信号检测的最佳检测器是能量检测器，但是能量检测器往往因为背景干扰的起伏和信噪比的劣化导致检测性能的下降。
