%X On the theoretical basis, using simulated and measured radar clutter data, we tested the inversion algorithm respectively. In simulated radar clutter data inversion, inversion results with and without considering the regularization item are discussed. In real radar clutter data inversion, dependence of the inversion results on the precision of the first guess values is discussed, in which the first guess values are either emperical model values or statistics inversion results, respectively. Finally, the advantages and disadvantages are compared between the variation adjoint regularization algorithm and the traditional statistical inversion algorithm, pointing out the direction of improvement in future work.
