摘要

Ghost imaging has been receiving increasing interest for possible use as a remote-sensing system. There hasnbeen little comparison, however, between ghost imaging and the imaging laser radars with which it would bencompeting. Toward that end, this paper presents a performance comparison between a pulsed, computationalnghost imager and a pulsed, floodlight-illumination imaging laser radar. Both are considered for range-resolvingn(three-dimensional) imaging of a collection of rough-surfaced objects at standoff ranges in the presence ofnatmospheric turbulence. Their spatial resolutions and signal-to-noise ratios are evaluated as functions of thensystem parameters, and these results are used to assess each system’s performance tradeoffs. Scenarios in whichna reflective ghost-imaging system has advantages over a laser radar are identified.
