Abstract:

A novel parameter estimation method for moving targets based on reconstructing signals and the L1 norm is proposed. The cost function is constructed by using the L1 norm of reconstructed signal and the data after clutter suppression. The parameters of the moving target can be estimated accurately with the proposed method when the pulse number of airborne radars is limited. The Cramer-Rao bound of parameter estimation for moving target is derived as well. The performance of the proposed method is verified through the numerical simulations compared with the Cramer-Rao bound.
