电子学在天文研究中的一些应用

天文学的研究完全基于对宇宙中天体电脑波辐射的探测和理解，电子学在各种探测过程和信号分析中起着不可或缺的作用。目前国内、国际所有的天文观测设备都必须配备一流的甚至独一无二的电子设备。射电天文学研究天体的无线电波。这里介绍电子在天文研究中的一些应用，特别是射电天文的测量方法，详细介绍探测和研究一种发射脉冲信号的天体（脉冲星）的具体方法。

Electronics and Signal Processing in Astronomy

All Astromonical researches are based on the detection and understanding of the electromagnetic waves radiated fromastonomical objects in the universe. Electronics is fundamental for any instruments, and signal processing is necessary for the following analysis. The national and international astronomical instruments have always used most advanced electronic technology. Radio astronomy is specially good example for such an electronic applications, which receive and study the radio waves of cosmological objects. The general usage of electronics in astronomical instrumentation has been brielfly introduced. To illustrate specifically the technology, the approach for radio astronomy, as well as specially pulsar signal receiving and processing, are discussed in deatails.
