As an important observation measure of ship surface wind field, the shipborne anemometer can provide continuous wind-field records, which plays role in combating ships, safe navigation and takeoff landing shipboard aircraft. When passes through superstructure hull, airflow field layout area becomes distorted, thus increases measurement errors parameters. However, this error be corrected using optimal estimation strategy, more reliably accurately evaluate changes field. In study, based on computational fluid dynamics (CFD) theory, characteristics were simulated CFD theory. The relationship between its placement was studied, with relatively less turbulence effect indicated. bias at different locations corrected, four-anemometer weighted fusion (FAF) correction combined FAF (FAF-BC) algorithm proposed to estimate parameters surface. Performance two algorithms evaluated under ideal, noise, temporal uncertainty noise conditions. Compared common dual-anemometer (DAT) algorithm, results conditions indicate that absolute direction (MAE) FAF-BC are reduced by least 2.80° 7.99°, relative speed (MRE) 11.09% 13.45%, respectively, stable.
