Infrared high-sensitivity imaging detection method and satellite-borne infrared camera

The invention discloses an infrared high-sensitivity imaging detection method and a satellite-borne infrared camera. A high-sensitivity infrared camera system comprises a linear high-gain infrared detector assembly, a low-temperature optical assembly and an information obtaining and processing integrated module. And the information acquisition and processing integrated module comprises a multi-path signal conditioning and acquisition circuit, an infrared background intelligent suppression circuit and an information processing and transmission circuit. The invention can effectively solve the problem that the existing platform cannot adapt to the condition that the size and weight of the imaging system are continuously increased to improve the signal-to-noise ratio and the optical aperture is continuously increased under the weak and small target imaging detection requirement, and avoids the problems of continuously repeated design and re-test verification. The system miniaturization under the same signal-to-no
