Motion Compensation in Six Degrees of Freedom for a MIMO Radar Mounted on a Hovering UAV

This paper deals with the motion of a hovering UAV with six degrees of freedom. The effects of the motion on the measured signal of a MIMO radar mounted underneath the UAV are analyzed. For each degree of freedom, namely the translation in x-, y- and z-direction as well as the rotation around x-, y- and z-axis, an algorithm is proposed to compensate the considered motion. The effectiveness of the proposed algorithms is demonstrated by measuring validated vital signs independent of the current UAV motion.
