Abstract

Recent work in optical autodyne techniques have presented the underlying theory and have investigated both S/N capabilities and measurement sensitivities for different target scenarios. Here we examine time-varying Doppler derived autodyne signatures of rotating targets. In contrast to heterodyne measurements of Doppler signatures, which may be related to projections of cross-range target scattering centers, autodyne measurements may be related to the autocorrelation of projected target scattering centers. It is shown that, under certain circumstances, application of reconstruction from projection techniques (e.g., backprojection) to time-varying autodyne signatures of rotating targets reconstructs the autocorrelation function of target scattering centers. For simple targets, the reconstructed auto-correlation function may aid in the determination of maximum target extents and target symmetries. Reconstruction techniques have been applied to both simulated and experimental autodyne data.
