Abstract：
An extension linear spectral model based on total least square algorithm is proposed, and iteratively abstract the better endmembers and physically based constrained algorithm with this model are presented. The results show that the proposed model provides better accuracy than traditional least square method, the total estimating precision improves by 10%-20%.
