1·For ship mounted sonar, the transducer received not only the required signal but also the ship noise. for distant signal, the ship noise is a strong interference.

在船用声呐环境中，基阵所接收的除了可能有的目标信号外，还存在本舰噪声，它对于远方的目标信号是一个强大的干扰源。

2·If they're right about what ET would do, so many people listening to so rich a region of the sky might even pick up the telltale signal of intelligent life on a distant world within a few years.

也包括电视卫星接受器。如果他们了解外星人要做什么，很多人听到天空中一个区域里不同的声音，在数年之内，甚至有可能接收到遥远的世界里外星生物的信号。

3·This paper discusses the key technologies for the design of signal collection circuit in distant electrocardiogram monitoring system, and presents an idiographic actualizing scheme.

讨论了远程心电监护系统中的信号采集电路设计的关键技术。提出了特色鲜明的具体实现方案。

4·The condition and composition of this signal transmission structure, supply of the field meter with power, distant transmission of signal and the explosion-safe problem are discussed in this paper.

本文对其应满足的条件、结构，现场仪表的供电、信号远传及防爆等问题做了较详细论述。

5·In ideal circumstances, the back scattered echo signal of SAR is chirp signal. With synthetic aperture theory, high azimuth resolution imaging to distant targets can be attained.

理想情况下，SAR回波多普勒信号是线性调频信号，采用合成孔径原理提高方位向成像分辨率。
