Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology. Research Laboratory of Electronics Nair, Ranjith Yen, Brent J. Shapiro, Jeffrey H. Quantum Communications and Quantum Imaging IX San Diego, California | August 21, 2011 Theory has shown [1] that the quantum enhancements afforded by squeezed-vacuum injection (SVI) and phasesensitive amplification (PSA) can improve the spatial resolution of a soft-aperture, homodyne-detection laserradar (ladar) system. Here we show they can improve the range resolution of such a ladar system. In particular, because an experimental PSA-enhanced system is being built whose slow photodetectors imply multi-pulse integration, we develop range-measurement theory that encompasses its processing architecture. We allow the target to have an arbitrary mixture of specular and speckle components, and present computer simulation results demonstrating the range-resolution improvement that accrues from quantum enhancement with PSA.
