In order to overcome the shortcomings of the Beihang University of Aeronautical and Astronautics inertial terrain-aided navigation II (BITAN II) algorithm, which is based on extended Kalman filtering, a novel algorithm combined with the terrain contour matching (TERCOM) algorithm and particle filter is proposed. Compared with BITAN II, the proposed algorithm involves a new algorithm framework, acquisition...
A method to determine the optical parameters of polymer thin film by use of the transmission spectrum is proposed, with the improved simulated annealing algorithm developed to perform its inverse calculation. A special phenomenon due to the almost equal refractive index between film and substrate, that is, the small waves on spectrum curves which make the information of film thickness losing, has...
