Laser Doppler 3D Navigation System Scheme
摘要
Abstract
In order to solve existing bottleneck of laser Doppler velocimeter (LDV) in the 3D navigation application, study on the laser Doppler velocity measure problem of aircraft flying in horizontal and turning mode. We treat the attitude angles of aircraft as unknown variables to resolve, which is quite different from the way considering attitude angles as error factors in existing references. Using Doppler’s frequency shift theory, the corresponding laser Doppler navigation equations were established, the equation to compute velocity and attitude of aircraft was obtained by deduce, thus the navigating calculation of aircraft in horizontal and turning mode was realized. The simulation results verified the correctness and effectiveness of our method which the aircraft real value is basically meet the estimation value.关键词
