Described are systems and methods that compensate for phase aberration in a high energy laser (HEL) without the need for a “beacon” laser or a wave front sensor to measure the phase aberration in the return signal from the “beacon” laser. In one aspect, the systems and methods use an imaging camera to image a HEL hit spot on a target, estimate the phase aberration of the HEL at the target based on the image of the HEL hit spot, and compensate for the phase aberration in the HEL using the estimated phase aberration. Also described are systems and methods that clean up an image of a target by estimating a wave aberration of an incoming beam based on the image of the target and clean up the image of the target using the estimated wave front aberration.
