| 摘 要： | Dynamic detection based on optics sensors and ranging radars is a new method to detect the luminous intensity of flight aid lights. The optics sensors can get the illumination information of each light, the ranging radar gets the distance information, and then data amalgamation technology is used to compute the luminous intensity of each light. A method to modify the errors of this dynamic detection system is presented. It avoids the accumulation error and measurement carrier＇s excursion error by using peak value detection based on optics sensors to estimate the accurate position of each light, then to modify the lights＇ lengthways distance information and transverse position information. The performance of the detection and ranging system is validated by some experiments and shown in pictures.

A method to modify the errors of this dynamic detection system is presented. It avoids the accumulation error and measurement carrier's excursion error by using peak value detection based on optics sensors to estimate the accurate position of each light, then to modify the lights' lengthways distance information and transverse position information.
