Paper Abstract

The Air Force Phillips Laboratory is in the process of demonstrating an advanced space surveillance capability with a heterodyne laser radar (ladar) system. Because coherent detection is used and the range resolution is obtained by the narrow pulse widths, satellite images can be reconstructed in two ways. The first is to convert the ladar returns into intensity projections, and then use tomographic techniques to create the image. The second approach is to use synthetic aperture radar methods which reconstruct the E-field image of the object and then square the result to get an intensity image. In this paper, these two methods are compared using computer simulations. It is shown that images reconstructed from intensity projections are of much higher quality than images reconstructed from E-field projections. This is shown to be true for both high and low light levels, and for full or limited sets of views.
