According to one embodiment, a radar tracking system includes a radar coupled to a radar processing system. Radar processing system receives images from the radar and that are each obtained at a differing angular orientation of the radar to a target. Radar processing system dithers each image along its azimuthal extent and then combines the dithered images to form an enhanced image of the target.

What is claimed is: 1. A radar tracking system comprising:a radar comprising a single-channel receiver that receives a beam of reflected electro-magnetic energy; anda radar processing system coupled to the radar and operable to:physically scan the radar, using a motor drive device coupled to the radar, through an arc having an angular length;select the angular length of the arc according an estimated location of the target;receive a plurality of radar images from the radar, each of the plurality of images obtained at one of a plurality of angular orientations of a boresight direction of the beam relative to a target, the target having a target location that is within the angular length of the arc;determine a boresight correction factor of the beam according to a terrain feature location of a terrain feature in each of the plurality of radar images and a known terrain feature location of the terrain feature, the known terrain feature location determined according to a radar location and information associated with the terrain feature, the information received from one or more records stored in a memory;adjust the one angular orientation of each of the plurality of images according to the boresight correction factor;adjust a range measurement of the target from the radar according to a tropospheric range correction factor and a calibration range correction factor;dither each of the plurality of radar images along an azimuthal extent of the each image; andcombine the plurality of dithered radar images, using a kalman filter, to generate an enhanced image of the target.
