Real aperture imaging of a small boat at 94GHz

This paper investigates the feasibility of real-aperture imaging a small boat by exploiting the good range resolution of a millimetre wave radar, and the known trajectory of the target. Two different image types are generated, one that includes the uncertainty in the angle of arrival introduced by the antenna beamwidth and uses the largest return only, and the other which exploits the complete range-amplitude return to obtain more information about the size of each target and its position on the boat. This second method produces images which are easier to interpret and could possibly be used to identify a target.
