| Abstract: |
| Through studying on Markov estimation algorithm for multistatic
radar positioning, a simplified positioning algorithm is propos
ed to solve the problem that error covariance matrix is nonpositive definite.
Simulation and analysis of the GDOP(Geometrical Dilution of Position) curv
e prove that this positioning algorithm is effective, and the co
mputation efficiency is remarkably improved. |
