Doppler Spectra of Radar Clutter

Abstract

Radar clutter spectra having sufficient dynamic range and resolution to permit shape estimation are reviewed. All are found to be distinctly non- Gaussian. A clutter scatterer motion model that includes correlation of velocities is defined and supported by empirical data for the case of wind fields. The Doppler spectra of scatterers with correlated motions are computed. Improvement factors for binominal-weighted moving-target indicators (MTI) are computed for several analytic spectrum functions that bound various observed features of empirical spectra.
