With a scientific educational purpose, "The Radio Waves" is a science documentary series with 8 episodes. The series is designed mainly for general public who have little knowledge of radio waves and its application in real life.
More than one hundred probes have been launched to the moon, the planet nearest to the earth, since the 1950s.Due to the limitation of signal blind zone, the probes have not been able to land on the far side of the moon.China's Chang'e 4 has become the first successful soft-landing probe on the far side of the moon. It is because the Magpie Bridge relay satellite provides continuous relay communications between the earth and the lander on the far side of the moon. In fact, space probe has the same principle to transmit and receive signal as that of our mobile phone. Radio waves are generated by electromagnetic oscillator at the transmitter, and then coupled by antenna at the receiver, later converted to circuit signals for further analysis and processing. Radio wave is not only used for communication and control, but also used for ranging, positioning, timing, diagnosis and treatment of diseases, and even heating matter. Looking forward to the future, our country's 5G communication applications, including the Internet of Things, the Internet of Vehicles, the Industrial Internet, as well as automatic driving, are closely related to radio, and they cannot be separated from the support of radio.Radio spectrum, in fact, is a natural resource. It plays an important role in daily life, economic development, national security, scientific research, social management and emergency rescue.
Now, let's start the journey of revealing the secrets and get to know the indispensable friend who is always with us.
