Ghost imaging has been receiving increasing interest for possible use as aremote-sensing system. There has been little comparison, however, between ghostimaging and the imaging laser radars with which it would be competing. Towardthat end, this paper presents a performance comparison between a pulsed,computational ghost imager and a pulsed, floodlight-illumination imaging laserradar. Both are considered for range-resolving (3D) imaging of a collection ofrough-surfaced objects at standoff ranges in the presence of atmosphericturbulence. Their spatial resolutions and signal-to-noise ratios are evaluatedas functions of the system parameters, and these results are used to assesseach system's performance trade-offs. Scenarios in which a reflectiveghost-imaging system has advantages over a laser radar are identified.
