Claim 2:
3. An apparatus comprising:
at least one processor configured to:
generate, based on an output of a Doppler sensor that is based on (i) local oscillator (LO) illumination and (ii) a first portion of return illumination that comprises coherent flood illumination reflected off a remote object, Doppler shift data for a Doppler shift corresponding to a longitudinal velocity of the remote object relative to a coherent imaging system;
receive, from a focal plane array, light intensity data that is based on (i) a second portion of the return illumination and (ii) Doppler-shifted LO illumination that is based on the Doppler shift data;
generate, based on the light intensity data, an image of the remote object;
employ at least one of the output of the Doppler sensor or the light intensity data from the focal plane array to determine a wavefront error; and
control a deformable mirror to modify high energy laser (HEL) illumination that is directed at the remote object in order to at least partially compensate for the wavefront error.
