Abstract: |
A new approach for gesture angles estimation based on single vector senso
r is presented.The single vector sensor mounted on aircraft receives polariz
ed electromagnetic signal from ba
se station. MUSIC algorithm is introduced to
estimate DOA and polarization parameter of the signal. Then the transformation m
atrix(Aircraft Attitude Matrix) from body coordinate to geographic coordin
ate is calculated with this estimation and the gesture angles are estimated. Mat
l
ab stimulation results verity the efficiency of the method. The error is within
1.2 degree and satisfies the a
ircraft control requirement. |
Key words: aircraft control vector sensor gesture angles polarized electromagnetic wave |
