Abstract

The Air Force Phillips Laboratory is in the process of demonstrating an advanced space surveillance capability with a heterodyne laser radar (ladar) system to be used, among other applications, for range-resolved imaging. Recently, image domain signal-to-noise rations (SNRs) have been derived both for the intensity projections calculated from the range-resolved reflective data and for image information obtained using linear combinations of the projections. Also, other recent results have indicated that superior image quality is obtained by first converting the heterodyne returns into intensity projections before using tomographic techniques to reconstruct an image, as intensity projections is validated using a laboratory heterodyne setup. In addition, the laboratory results are used to validate the conclusion that intensity projections provide superior image reconstructions.
