Author Affiliations +
In this paper, the phase of a radar range profile is shown to contain valuable information for inverse scattering problems. A physics-based high-frequency parametric model is adopted for the radar backscatter, and information is quantified using the variance of parameters estimated from noisy radar range profiles. Through analysis of the Fisher information matrix, phase is observed to yield up to a factor of ten increase in achievable resolution; moreover, phase is shown to allow reliable discrimination of frequency-dependent scattering behaviors. Results are confirmed using measured radar imagery from a 2-inch resolution X-band system.
