"For the new journey to build a new era, the new era · extraordinary ten years" from zero dreams and dreams of deep space

After 10 years of hardships and fulfilling innovation, the Chinese space meets the radar technology and ranks among the world's first -class. The microwave radar team led by Sun Wu also measures the new journey of dreaming deeply with solid footsteps. "In the past 10 years, we have participated in major aerospace projects such as space station construction, lunar exploration projects, and Mars detection, and have achieved three first and ten games." Said Sun Wu, chief designer of the 25 microwave radar in China Aerospace Science and Technology House.

When it was still blank in relevant domestic fields, Sun Wu has led the team to start the independent development of microwave radar principles. From scratch, technical tackling, day after day, testing, pondering, changes, and re -tests ... After breaking through key technologies, microwave radar joined the man manned space career, and in Shenzhou 8 unmanned spacecraft and Tiangong Yiyi The "first show" was completed in the first meeting of the docking mission.

"One in place" is a sentence that Sun Wu often said in the development of radar, and it is also a concrete manifestation of his insistence on the quality of quality of the "zero defect". During the development process, the team issued a combined task book to clarify the design specifications and requirements, and consider a series of special environmental requirements in advance. , Greatly improve work efficiency.

The weight is reduced by half, the volume is reduced by two -thirds, and the power consumption is reduced by one -third, which means that it can be measured more accurately in space and work longer ... On October 19, 2016, the team independently developed by the team The second -generation high -precision measurement microwave radar helped Tiangong No. 2 and Shenzhou 11 "Space Hand".

"In the past 10 years, our microwave radar has continued to output high -precision capabilities. I was fortunate to participate in witnessing the vigorous development of China's aerospace industry. We are moving forward to exploring the new journey of space with a more stable step!" Sun Wu said.

Another goal of microwave radar team is interstellar detection. Provide measurement methods for landing Mars for "Tianwen No. 1" -develop phase control array sensitive. The development team is a young team. After 5 years of careful polishing, the established goals with smaller product volume, lighter weight, more complete function, and higher accuracy have been realized. Essence On May 15, 2021, the "Tianwen No. 1" detector successfully landed on Mars and took an important step in my country's interstellar detection journey. The phase -control array sensitive device does not humiliate the mission, and realizes the first successful application of the landing measurement measurement of the ground body. It spans 320 million kilometers. The team engraved the mark of innovation, pioneering, and struggle.

"Ask the sky, the moon, and the Xinghe, how big is our dream, how big is our dream." This is the team's personal perception over the past 10 years.

In the early morning of December 17, 2020, the rock soil from Chang'e 5 returned to the earth, which also means that microwave radars have been successfully applied again in the field of space that are more far away from the earth. "We will continue to play the power of scientific and technological support!" Sun Wu said, from "nine days to the moon" to "hand -picked stars", they will continue to work hard to strive to be the strugglers and climbers of the Chinese aerospace industry in the new era.
