Design of optical surveillance system for balloon-base load cabin in near space

Abstract

Near space usually refers to the earth space with a height of about 20-100 km. It is a highly interdisciplinary field involving atmospheric physics, space physics, plasma physics, photochemistry, solar and geosciences, Geosciences and life sciences. The development and utilization of near space is far less than that of traditional airspace and satellite orbital space. Near space usually corresponds to areas where traditional airplanes are difficult to fly and satellites are not easy to detect. Compared with the middle and lower atmosphere and higher ionosphere and outer space, there has been a lack of systematic and efficient observers in the near space for a long time. Objectively, near space has become a weak point of human's understanding of the whole earth's space.
