Paper Abstract

Coherent laser radars used for 3-D imaging and aerosol/pollutant sensing collect target returns which comprise a range-spread speckle process. This paper addresses a class of waveform design/waveform evaluation problems for such radars. The maximum-likelihood (ML) processors and Cramer-Rao (CR) performance bounds are developed for short pulse, chirped pulse, sinusoidal amplitude-modulated pulse, and sinusoidal frequency-modulated pulse wave-forms. All four of these waveforms are shown to have nearly identical ultimate range accuracies. However, range accuracy is not the only performance criterion of interest; range resolution, ambiguity, and anomaly must also be considered. Analysis and discussion of some of these aspects of waveform selection are included in the paper.
