Further Information

Tomography is an established imaging method used to reconstruct images from projection data. The projections can consist of E-field data (for example, synthetic aperture radar data) or intensity data (e.g., X-ray data). For short pulse length coherent laser radars, however, the projection data is available in either form. In this paper, the signal to noise ratios (SNRs) in the reconstructed images for each type of data are presented and analyzed to determine which type of data produces the best image quality. It is shown that the SNR at any point in the image domain is limited above by one when using E-field data, but can be as high as the square root of the number of projections when intensity projections are used. These theoretical results are illustrated using computer-simulated data.
