Radar, also known as radio detection and ranging, has played a vital role in different roles of war, meteorology and civil affairs in the past 60 years. It develops faster than any military equipment and is used in almost every country. Radar is a force that cannot be ignored in the development of civilization.

The embodiment of measurement and control technology in radar technology system can not be ignored. As a pilgrim of core technology, it is necessary to know the countless pulses of radar from the beginning. From today, Huasui Science and Technology House will trace the source of radar with you, from the past to the future, share bits and pieces about radar, and learn about this mysterious and ubiquitous country together.

Application of radar;

The advantage of radar is that it can detect long-distance targets day and night without being blocked by fog, clouds and rain. It has the characteristics of all-weather and all-day, and has certain penetration ability. Therefore, it is not only an indispensable military electronic equipment, but also widely used in social and economic development (such as weather forecast, resource exploration, environmental monitoring, etc.). ) and scientific research (celestial research, atmospheric physics, ionospheric structure research, etc. ).

Spaceborne and airborne synthetic aperture radars have become very important sensors in remote sensing. A radar targeting the ground can detect the precise shape of the ground. Its spatial resolution can reach several meters to tens of meters, regardless of distance. Radar also shows good application potential in flood monitoring, sea ice monitoring, soil moisture survey, forest resources inventory, geological survey and so on.
