Abstract:

The influence of wind on UAV’s track angle is analysed. A reference velocity is defined as the combination of airspeed vector, wind and target velocity, and the moving target tracking in wind is transformed into static target tracking with a reference velocity, a new guidance law is designed for UAV ground target tracking in wind based on the static target tracking guidance law, which makes the reference velocity be perpendicular to the camera line-of-sight and maintains a designed horizontal distance between UAV and target. The guidance law is validated by target tracking simulation with different wind speeds.
