Abstract: |
A new parameter-correction technique is proposed, which can calibrate the radio
meter shaft parameters by means of radar-theodolite joint star observati
on.The related model is derived and linked with practice.By using t
his technique,the related task data is analyzed. The results indicate that the
ship-borne radio shaft parameters corrected by the dynamic calibration can elim
inate the error between the radio optical axis and theodolite optical axis. The technique
can obviously improve the measurement accuracy of the ship-borne radio system. |
Key words: ship-borne radar shaft parameter dynamic calibration |
