Abstract

The invention discloses a geostationary orbit high-resolution infrared area staring camera system, comprising: a geostationary orbit infrared shading cover, a geostationary orbit infrared optical system, a focusing mechanism, an earth orbit infrared calibration component, a geostationary orbit infrared Large area array focal plane assembly, refrigeration assembly, geostationary orbit infrared signal processing device; among them, the infrared optical system collects the radiation signal of ground objects in the detection area, and the focusing mechanism makes the geostationary orbit infrared optical system output the corrected ground object radiation signal , the geostationary orbit infrared large array focal plane component samples the corrected ground object radiation signal and converts it into an electrical signal, which is input to the geostationary orbit infrared signal processing device, and the geostationary orbit infrared signal processing device amplifies and filters the electrical signal And the ground object image signal is obtained after encoding. The invention solves the difficult problem that the existing cameras cannot balance high temporal resolution and high spatial resolution.

Description

technical field [0001] The invention belongs to the technical field of aerospace optics remote sensing, in particular to a geostationary orbit high-resolution infrared array staring camera system. Background technique [0002] Geostationary orbit high-resolution detection technology has become an important aspect of the future development of earth observation technology at home and abroad because of its orbital characteristics, such as large detection range, long-term detection of hotspot areas, and all-day high-resolution real-time monitoring and detection. direction. [0003] High-resolution Low-Earth Orbit (LEO) infrared optical imaging remote sensing satellites have been widely used for many years, but with low temporal resolution. Geostationary orbit (GEO) meteorological satellites have higher temporal resolution and larger imaging swath, but lower spatial resolution. In order to meet the requirements of earth observation that require high temporal resolution and rela...
