摘要	Aiming at the short integral time and low signal-to-noise ratio(SNR) of the large field hyperspectral camera push-broom imaging, a new imaging mode of satellite with pitch motion compensation is proposed to increase the integral time, so that the SNR of the instrument can be improved. Firstly, the relationship between integral time and SNR is derived, and then the pitch angular velocity is calculated and utilized to make the satellite scan in a maneuverable manner. Finally, the on-orbit pitch motion compensation imaging test is carried out by ZH-1, and the remote sensing images with higher SNR than the conventional push-broom images are obtained, which validate the theory. The imaging mode proposed in this paper can not only improve the SNR without changing the inherent optical parameters of the camera, but also reduce the cost of hyperspectral camera and expand the scope of application.
