摘要

Accurate vehicle pitch and roll can be computed from a corresponding signal loop which receives inertial data input contaminated by the effects of gravity on a vehicle. Data from Doppler radar is compared to the inertial data and an error signal dependent on pitch or roll angle is substracted from the input inertial data resulting in the generation of accurate navigational parameters.
