A method for characterizing radar signatures using ARMA models is developed based on the concept of scattering centers. A parameterization of the ARMA model specific to the radar target identification problem is chosen, and several key improvements to the algorithm, including the use of singular value decomposition and the removal of spurious scattering centers are presented and compared to earlier versions of the algorithm. The resulting algorithm is tested with data taken from a compact range. These tests include comparison of different targets, different aspect angles and frequency ranges, as well as robustness tests on the algorithm and evaluation of performance in noise.
