Abstract
A gimbal-assisted continuous-wave (CW) Doppler radar detection system mountable to an unmanned aircraft system may be rotated in three degrees of freedom relative to the UAS to provide targeted multidirectional obstacle detection by transmitting CW signals throughout a field of view and analyzing reflected signals from obstacles within the field of view. The radar assembly may be articulated to provide track-ahead detection in anticipation of a heading or altitude change of the UAS, to center on a detected obstacle in order to classify or identify it more clearly. The radar assembly may be rotated below the UAS and its field of view changed to increase breadth and accuracy at a shorter effective range, in order to determine real-time altitude or terrain data while the UAS executes a landing.
