摘要：
提出了一种基于重构信号和1范数的动目标参数估计方法。该方法利用重构信号与杂波抑制后数据的1范数构造代价函数完成对动目标的参数估计,能够在雷达发射脉冲数有限的情况下获得准确的参数估计结果。给出了其对应Cramer-Rao界的详细推导过程；通过将仿真结果与Cramer-Rao界的比较,证明了该方法的有效性。
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.
