Space situational awareness system based on bionic polarization feature sensing and navigation information fusion

The development of novel principle photoelectric detection system is an important part of the construction of space situation awareness system. The imaging polarimetry has become a powerful tool to enhance the information available in a variety of space remote sensing applications. This paper presents a new space situational awareness system by imitating the structure and function of biology in nature. Inspired by the information awareness and navigation mechanism of the insect, birds and fish, we explore the science problem about environments information awareness and location measurement by means of model simulation, prototype construction and experimental verification, which based on the bionic polarization vision system. Bionic situational awareness system which fused the polarization image feature and navigation information is suggested. The information fusion and error analysis model based on bionic information perception and navigation is presented. A situational awareness prototype fused space feature acquisition and navigation is built up, the data update rate is higher than 25 Hz, and the angle measurement repeatability is within 0.05°. Polarization imaging situational awareness system function experimental results show that the bionic polarization detection method can reveal more details about the target feature information and enhance the effect of space target detection effectively, which fused the target light intensity, polarization degree and polarization azimuth information.
