Abstract

Distributed reconfigurable remote sensing satellite system can realize flexible and robust remote sensing network. Imaging system for distributed reconfigurable remote sensing satellite system should consume fewer power and be lighter to be installed on small or micro satellite. In this paper imaging system based on CMOS for distributed reconfigurable remote sensing satellite system was put forward. Circuits of CMOS sensor driving and CMOS data processing were detailed. In order to improve signal integrity circuits were divided into two sections which were connected with flexible printed circuit. CMOS sensor and its power circuits were placed in the focal plane printed circuit board. Imaging control box consisted of control and data processing circuits of CMOS sensor as well as communication and image data transferring circuits. Impedance matching was used to improve signal integrity of signals transmitted through flexible printed circuit between the focal plane printed circuit board and imaging control box. Results of experiments and analysis indicated that power dissipation of imaging system for distributed reconfigurable remote sensing satellite system was 4.05 W and the weight of imaging control box was 0.435 kg. SNR of each band of imaging system for distributed reconfigurable remote sensing satellite system was more than 41.28 dB as sun zenith angle is 20º and earth reflectance is 0.65.
