Usi g the system, microwave scatteri g coefficie t of soil i a differe t moisture a d rough ess w ere measured. After t hat, usi g IEM model to calculate data as artificial eural etwork trai i g data a d choosi g the M ulti a gle dualpolarized structure to be trai ed so that to ge erate parameter i versio of etw ork. Fi ally, put the measure data i to the et work to i versio parameter. Results show that I door scatteri g system is useful ot o ly has t he study the microwave scatteri g mecha ism of surface featured, but also for the i versio to provide the required data.
