Abstract: |
Aiming at the data fusion problem of simultaneous sensor measurements of differe
nt dimensions,this paper proposes a new algorithm in which by use of the three d
imensional measurement (containing both distance and azimuth) a pseudomeasure
ment including target position and its corresponding covariance is constructed f
or the deficient dimensional measurement (only having distance or only having az
imuth). The computer simulation shows that it can use the data of different dime
nsions effectively and can improve the target location precision greatly.
The proposed algorithm has some applied value in the future. |
