基于迭代UH∞的单站无源定位算法
Single-observer passive localization algorithm on basis of iterative UH∞
摘要
Abstract
Aiming at such defects of the single-observer passive localization system as weak observability, inferior filtering stability, slow convergence speed and low filtering precision, a kind of iterative unscented H∞( IUH∞) fil-tering algorithm was presented. In the algorithm, the unscented transformation ( UT) was introduced into the ex-tended H∞ filtering, so as to avoid the calculation on linearized Jacobian matrix and enhance the filtering effect. Under the constraint condition of iterative judgment criterion, the state vector and the covariance matrix were esti-mated by repeatedly utilizing the observation information to make them more tend to the true value. The simulation results show that, under different observation precisions, this algorithm has the following merits: better stability, convergence speed and positioning precision.关键词
