Study of the Method of Wind Estimate Based on Measuring Air Data

Wind estimation methods based on air data computer are studied to deal with the error of the dispenser caused by constant wind. The arithmetical method of wind estimate for opening guidance loop with long range, invariable speed and height cruise missile and the method of wind estimate for closing guidance loop with short range and passive sliding trajectory air-to-ground dispenser were proposed, respectively. The 6-DOF dynamic model for dispenser was given. The method of wind estimate for closing guidance loop was proved through the simulation. The results show that the accuracy of the wind estimate is well enough to be used in engineering.
