On Wind Correction Alogorithm of WCMD

The wind field plays an important role in air-ground guided weapons. In this paper, we design a wind correction algorithm for WCMD based on the integrated navigation information. Firstly, the WCMD 6DOF simulation model is constructed in MATLAB / simulink environment, and the wind speed and wind direction in the horizontal plane are estimated by vector triangle method. The corresponding proportional navigation law is designed, which modifies the longitudinal and lateral deviation based on the estimated wind speed. Finally, the wind correction simulation of WCMD is performed, and the results show that the wind correction algorithm designed in this paper can ensure the submunitions landing accuracy.
