In order to solve the problem that the results of automatic target recognition of SAR images using exist some methods are still not satisfactory,three methods are proposed in this paper for automatic target recognition of SAR images,that is,target recognition using intensity features,target recognition using grid features,and target recognition using template features.

Based on the hydrodynamic energy transport model, the port electrical characteristics of groovedgate PMOSFET′s are studied, including gate characteristics, drain characteristics and hotcarriereffects.
