An analytical expression for the Doppler spectrum of forest clutter

The dominant effect of the clutter Doppler spectra on coherent radar performance needs a detailed study of the Doppler process in the clutter. This paper introduces a method for characterizing the statistical properties of Doppler velocity of the radar clutter echoes from forest terrains. In this paper, a modified model is derived for the Doppler spectrum. The derived model provides a theoretical basis for the spectral shapes observed in the measurement tests for common ground clutter. The method presented here is directly applicable to many problems in the simulation of Doppler processes.
