Assignee: RAYTHEON COMPANY
Field: Measurement (Instruments)
Classification: CPC G  F | IPC F  G

Claim 10:
11. A method comprising:
generating, 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;
receiving, 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; and
generating, based on the light intensity data, an image of the remote object;
wherein the light intensity data is also based on (i) Doppler-shifted high energy laser (HEL) LO illumination and (ii) at least a portion of HEL return illumination that comprises HEL illumination reflected off the remote object; and
wherein the method further comprises controlling generation of the Doppler-shifted HEL LO illumination using the Doppler shift data.
