Description

technical field

[0001] The invention relates to an orienting device for faint targets in adjacent spaces based on color infrared spectrum common-aperture imaging, and belongs to the field of target recognition equipment in adjacent spaces. Background technique

[0002] Near space generally refers to the area between 20km and 100km from the ground, which is the area between the highest flying altitude of the aircraft and the lowest flying altitude of the space orbiter, and is the transition area from the aviation airspace to the aerospace airspace. From bottom to top, the adjacent space includes the stratosphere region, the middle atmosphere region and part of the ionosphere region. This region has the characteristics of thin atmosphere and weak meteorological activities. There are many unique physical phenomena in the adjacent space, and the atmospheric density changes drastically. For example, when rising from an altitude of 20km to an altitude of 40km, the atmospheric dens...
