Abstract

Observation target characters can be truly reflected by multi-type sensor detect with multi-source information fusion, processing and comparison. Based on the design and application requirement of multi-type sensor for low inclination orbit satellite(hereinafter called LIO), the study on optical remote sensor’s imaging performance is carried out in this paper for LIO satellite. Due to the complex precession of the orbit, the imaging characteristics are analyzed and compared with the sun synchronous orbit including solar elevation angle, radiance at the entrance pupil, SNR, revisit period, satellite illumination azimuth angle and the angle between sun vector and bore sight vector. According to the analysis results, conclusions on optical remote sensors imaging performance of LIO can be drawn in the imaging dynamic, radiance performance, revisit efficiency, sunlight avoiding and thermal control design. The study provides a reference for the low inclination orbit satellite general design and optic remote sensor development.
