1. A radar range translation compensation method, comprising: scanning a radar in a first direction with respect to a surface of a substrate, the radar being configured to construct an image of a target within or adjacent to the substrate according to scan points associated with the surface; while scanning the radar in the first direction, determining a range between the radar and a current scan point as well as determining the range between the radar and a future scan point displaced from the current scan point in the first direction; processing the determined ranges to estimate a range translation of the radar during the scan; and constructing the image of the target according to the scan points while compensating for the estimated range translation of the radar.
