1. A system comprising:
a radar assembly configured to be mounted to a mobile structure, wherein the radar assembly comprises an orientation and position sensor (OPS) coupled to or within the radar assembly and configured to provide orientation and position data associated with the radar assembly; and
a logic device configured to communicate with the radar assembly, wherein the logic device is configured to:
receive radar returns corresponding to a detected target from the radar assembly and orientation and/or position data corresponding to the radar returns from the OPS;
determine a target radial speed corresponding to the detected target based, at least in part, on the radar returns and the orientation and/or position data corresponding to the radar assembly; and
generate radar image data based, at least in part, on the radar returns and the target radial speed.
