射电波

空间飞行器低频率宽频带射电波接收天线的设计探讨

Design of Radio Wave Receiving Antenna with Low Frequency and Broad Band for Space Vehicle

但有些恒星，所谓的脉冲星，会有规律地发出射电波脉冲。时域反射器（DR）一个脉冲发射给环路。

But certain stars , called pulsars , give off regular pulses of radio waves . Time-domain reflectometry ( TDR ): An impulse is transmitted into the loop .

测定穿过太阳附近的宇宙射电波的色散度也可以获得许多资料。

Much data can be obtained by measuring the dispersion of cosmic radio waves passing near the sun .

在地球的大气层以内，只能对射电波、近红外波和可见光波进行研究。

Only radio , near-infrared , and visible light waves can be studied within the earth 's atmosphere .

近年来通过对微波背景辐射及遥远射电星系发出的射电波的观测表明，它们存在一与地球运动相关的各向异性。

Recent observations on microwave background radiation and distribution of distant radio galaxies demonstrate that there exists dipole anisotropy in relation to the motion of the Earth .
