The application of spread-spectrum system in the area of remote space exploration

Abstract

Following the great success of satellite application and aerospace engineering,China has formally startedup moon exploration project,in the future China will execute exploration of more remote object.In this paper, combining the development step of Chinese deep space exploration, the author introduces the current situation of deep exploration techniques home and abroad, meanwhile the author briefly compares the advantage and disadvantage of spread-spectrum deep exploration system and USB deep exploration system, and the author also briefly describes the important status of intending spread-spectrum deep exploration system in the area of deep space exploration. According to the characteristic of deep space exploration, this paper analyzes the problem and key techniques such as spread-spectrum measurement system of remote space orbit, reception of the weak signal and high efficient coding and decoding, super large aperture antenna and antenna array combination technique, high power control amplifier technique, insulating of transmitting and receiving signals applied in deep space exploration,at the same time,the author proposes evolution suggestion of spread-spectrum exploration technique applied in deep space exploration. Meanwhile,through combining the current situation of spread-spectrum exploration system home and abroad,the author analyzes a few key techniques of spread-spectrum exploration system applied in deep space exploration.
