Research on adaptive normalization method for attitude measurement of rotating projectile based on four-axis infrared

Abstract

In view of the problems that the current attitude measurement method of rotating projectile based on three-axis infrared needs to normalize the sensor according to the surrounding environment in advance, resulting in the troublesome application of infrared attitude measurement method and insufficient environmental adaptability, an adaptive normalization method for attitude measurement of rotating projectile based on four-axis infrared is proposed. Based on the mathematical relationship between four-axis infrared sensors, an adaptive algorithm for the output amplitude and offset of infrared sensors is designed, which can realize the adaptive normalization of the environment of infrared sensors at any time. By building the semi-physical experiment and changing the surrounding environment, it is proved that the adaptive normalization method of rotating projectile attitude measurement based on four-axis infrared is effective, which provides convenience for the use of infrared attitude measurement method and further improves the infrared attitude measurement theory.
